Best Short Throw Projector When Wall Space Is Tight

The best short throw projector for swimmers is the TOPTRO Portable Smart Projector, because at 2.64 lb with a 5.55 x 7.63 x 6.22 in body and a 2-year warranty, it moves between rooms without becoming a project. If you need a picture that survives a lit room, the ViewSonic PS502W is the better buy at a claimed 4,000 ANSI lumens. Throw ratio is what separates these five, and it varies more than the price does.

Here's the 30-second shortlist. TOPTRO for portability, ViewSonic for brightness, and the YQHS if the wall is barely more than a foot away.

Best short throw projector for swimmers at a glance

What actually decides a short throw projector purchase?

Most guides for this category compare resolution. Four of these five list 1080p, so resolution decides nothing here. The number that changes your room is throw ratio.

Throw ratio is the distance from lens to wall divided by image width. A 0.5 ratio means half a foot of distance per foot of picture. ViewSonic claims 0.5 and says the PS502W puts a 100-inch image up from 4.5 feet. YQHS claims 0.65:1 and describes a 60-inch image from very close range. iSinbox claims 1.1:1 and 100 inches from 7.9 feet. That's a 3.4-foot swing between two listings that both use the words "short throw".

Second criterion: weight, because it decides whether the thing lives on a shelf or in a bag. The spread here is real. 1.46 lb for the YQHS against 6.85 lb for the Optoma is more than four times the mass.

Third: warranty, and only because the coverage is uneven. Three of the five publish two years or better. The Optoma publishes one year on the projector, and it sits at the top of the price ladder in this set.

Brightness matters too, but only one listing here publishes a lumens figure you can compare against anything.

How I weighted the criteria across five listings

I lined up the published specifications side by side and scored them in this order, heaviest first.

1. Throw ratio or stated distance, 40%. It's the defining trait of the category and the only spec that changes where furniture goes.
2. Portability, 25%. Weight and dimensions, both published for four of the five.
3. Warranty, 20%. Length and whether parts and labour are named.
4. Platform and connectivity, 15%. Built-in apps versus dual HDMI, because those serve different buyers.

Brightness sat outside the weighting on purpose. Only ViewSonic publishes an ANSI figure, and YQHS states 350 lumens without naming a standard. Scoring a category on a number four listings don't publish rewards the loudest listing, not the best projector.

Why these weights? Because a short throw projector is bought to solve a distance problem. Everything else on the spec sheet is available from a normal projector too.

1. TOPTRO Portable Smart Projector — Best overall

The TOPTRO wins because it's the only pick that pairs a full smart platform with a body light enough to carry one-handed and a 2-year warranty behind it.

Best for: someone moving one projector between rooms and trips Skip it if: you need brightness for a lit room

At 2.64 lb and 5.55 x 7.63 x 6.22 in, this is the second-lightest pick and the smallest footprint on a shelf. TOPTRO says the unit runs Google TV 14.0 with access to more than 10,000 apps and voice control, and that it supports WiFi 6 and Bluetooth 5.3. The listing describes native 1080p with 4K decoding, meaning it reads 4K files and displays them at 1080p. That's an honest framing and worth reading carefully, because it isn't a 4K picture.

TOPTRO also claims an AI setup routine covering focus, keystone, obstacle avoidance and screen fit, plus a built-in rotatable stand. The 2-year warranty matches the two other picks that publish one and beats the Optoma's single year.

The trade-off is brightness. No lumens figure appears anywhere in this listing, and the ViewSonic publishes 4,000 ANSI lumens. In a room with daylight, that gap is the whole ballgame. Only one seller lists the TOPTRO, so you're buying from a single source.

Pros:

• 2.64 lb, second-lightest in this set
• Smallest published footprint of the five
• 2-year warranty, matching the best coverage here
• Google TV 14.0 platform per the listing
• Rotatable stand claimed as built in

Cons:

• No brightness figure published at all
• No stated throw ratio, only "ultra short throw"
• 1080p output, not true 4K
• Only one seller lists it

2. iSinbox Short Throw Projector 4K — Most versatile

The iSinbox is the pick that publishes a real throw ratio and a real distance, which makes it the easiest of the five to plan a room around.

Best for: a shared living room where the projector stays put Skip it if: you carry it daily

iSinbox states a 1.1:1 short throw ratio and a 100-inch image from 7.9 feet, and that pairing is the most useful sentence in these five listings. You can measure 7.9 feet with a tape and know what you're getting. The AC311 weighs 4.25 lb in white-gray, and iSinbox describes a dual-mode build where a 360-degree stand doubles as a handle.

The listing claims Netflix compatibility with a built-in smart TV system, native 1080p with 4K HDR10+ support, AI autofocus and 6D keystone. Warranty runs 24 months, level with the TOPTRO and the YQHS. It sits second-cheapest in this set, which is the strongest position-to-specification pairing here.

Two honest problems. That 1.1:1 ratio is the longest of the three published ratios, so it needs more distance than the ViewSonic or the YQHS for the same picture. And at 4.25 lb it's 1.6 lb heavier than the TOPTRO, enough to feel it in a bag. Dimensions aren't published, so you can't check shelf clearance before it arrives.

Pros:

• Publishes both ratio and distance: 1.1:1, 100 inches at 7.9 feet
• Second-cheapest of the five
• 24-month warranty
• Handle-and-stand design per the listing

Cons:

• Longest published throw ratio in this set
• 4.25 lb, heavier than two lighter picks
• No dimensions published
• Only one seller lists it

3. YQHS Android 14 Ultra Short Throw — Best budget pick

The YQHS is the cheapest and lightest pick here, and the 0.65:1 claimed ratio means it gets closer to the wall than anything except the ViewSonic.

Best for: a small bedroom wall at close range Skip it if: you want a screen past 60 inches

At 1.46 lb and 6 x 5.4 x 5.4 in, this is the lightest of the five by a wide margin, roughly a fifth the weight of the Optoma. YQHS claims a 0.65:1 ultra-short throw and a 60-inch image from very short range. The yellow finish is the only non-black or non-white body in the set.

The listing states 350 lumens, 1080p, HDR10 and HLG support, Android 14 with Netflix, Prime Video and YouTube built in, and TOF laser autofocus that locks in about three seconds. Power runs through a USB-C PD interface with a 45W GaN adapter, which YQHS credits for the smaller body and better heat handling. Warranty is two years from the manufacturer. Two sellers list it, the joint-highest in this set.

The 350 lumens figure is the catch, and it's the reason this is the budget pick rather than the overall one. That's a dark-room number. The listing also anchors its example at 60 inches rather than 100, which suggests where this projector is comfortable. Cheapest of the five, and the specification sheet reflects it.

Pros:

• Cheapest of the five
• 1.46 lb, lightest here by a clear margin
• 0.65:1 claimed ratio, second-shortest in this set
• 2-year manufacturer warranty
• USB-C PD power per the listing

Cons:

• 350 lumens is a dark-room figure
• Example screen size given as 60 inches, not 100
• No standard named for the lumens claim
• Smallest published dimensions also mean the smallest speaker cabinet

4. ViewSonic PS502W WXGA — Best upgrade

The ViewSonic is the only pick with a published ANSI brightness figure, and 4,000 lumens is what buys you a watchable picture with the lights on.

Best for: a bright room, a classroom or a garage Skip it if: you want streaming apps built in

ViewSonic publishes 4,000 ANSI lumens, a 0.5 throw ratio, WXGA 1280x800 resolution, screen sizes to 150 inches and a 100-inch image from 4.5 feet. That 4.5-foot figure is the shortest published distance for a 100-inch picture in this set, 3.4 feet closer than the iSinbox. Released in 2023, model PS502W, 6.3 lb, 4.5 x 12.2 x 9.2 in.

The warranty is the strongest here by some distance: three years limited on parts and labour, one year on the lamp, plus a first-year Express Exchange service. Dual HDMI and vertical auto-keystone are listed, and ViewSonic credits its SuperColor processing for the colour gamut.

Two real costs. WXGA at 1280x800 is the lowest resolution in this comparison, and on a 100-inch wall you'll see it against the 1080p picks. And there's no smart platform: no built-in apps, no Netflix, so you're supplying a stick through one of the HDMI ports. It's also the second-most expensive pick and a lamp-based design, which means a consumable the LED and laser picks don't have.

Pros:

• 4,000 ANSI lumens, the only standardised brightness figure here
• 0.5 throw ratio, shortest published in this set
• Three-year parts and labour warranty
• 100-inch image from 4.5 feet
• Dual HDMI inputs

Cons:

• WXGA 1280x800, lowest resolution of the five
• No built-in streaming apps
• 6.3 lb and the widest body at 12.2 in
• Lamp warranty is only one year

5. Optoma ML1080UST Photon Go — Best premium

The Optoma claims a 10-inch throw distance and triple-laser RGB, the two most ambitious specifications in this set, but it publishes the least to back them up.

Best for: a permanent console under a wall-mounted screen Skip it if: you want published specifications before buying

A 10-inch throw distance is the shortest claim of the five, and it changes the install completely: the projector sits on a console against the wall rather than out in the room. At 6.18 x 9.92 x 2.56 in, this is the flattest body here, and that 2.56-inch height is what lets it hide under a screen. Model ML1080UST, released 2025, 6.85 lb.

Optoma lists triple laser RGB technology, integrated Dolby Audio, 1080p and Google TV. A triple-laser light source is a different class of engine from the LED units elsewhere in this set, and it's the reason this pick sits at the top of the price ladder.

Now the problem. This listing carries three feature lines, each one a bare phrase. No lumens, no throw ratio, no image size at a given distance, no colour gamut figure. Compare that to ViewSonic publishing five specific numbers. The warranty is also the weakest here at one year on parts and labour, against three years from the ViewSonic and two from three other picks. It's the most expensive pick in this set and the heaviest at 6.85 lb, and you're buying largely on brand and the laser claim.

Pros:

• 10 in. claimed throw distance, shortest here
• Triple laser RGB light source per the listing
• 2.56 in height, flattest body in this set
• 2025 release, newest of the five
• Google TV and Dolby Audio listed

Cons:

• Only three feature claims published, the thinnest listing here
• No brightness, ratio or screen-size figure at all
• One-year warranty, weakest in this set
• 6.85 lb, heaviest pick
• Highest price position for the fewest published specifications

Can any short throw projector survive a pool deck?

Worth being direct about the swimmer angle, because none of these five listings mentions water resistance, an IP rating, or any sealed or splash-proof construction. Not one. If you want a projector near a pool, that's a judgment you have to make yourself, and none of these picks is documented for it.

What the listings do support is portability, which is the closest useful proxy. Three of these describe outdoor use: TOPTRO mentions travel and RV trips, iSinbox mentions campsite tables, YQHS names outdoor use in its title. Portability is what lets you carry a projector out for the evening and carry it back inside before anything gets damp.

If that's your plan, the practical checklist looks like this:

• Keep the unit under cover and back from splash range
• Weight decides how often you actually bother: 1.46 lb goes out, 6.85 lb stays in
• Ambient light outdoors after dusk is manageable; before dusk, 350 lumens won't cut it
• A wall or a sheet works, and a shorter throw ratio means less deck space consumed

None of that is a waterproofing claim. It's just how you'd handle an unsealed electronic device outdoors.

Throw ratio math: how far from the wall?

This is the arithmetic that makes a short throw projector worth paying for. Multiply the throw ratio by the image width in feet and you get the distance you need.

A 100-inch 16:9 screen is about 7.3 feet wide. Run the three published ratios:

1. ViewSonic, 0.5 — roughly 3.6 feet. ViewSonic publishes 4.5 feet, so treat their figure as the real one.
2. YQHS, 0.65:1 — roughly 4.7 feet for 100 inches, though the listing's own example stops at 60 inches.
3. iSinbox, 1.1:1 — roughly 8 feet, and the listing publishes 7.9 feet.

The Optoma's 10-inch claim sits in a different category entirely: that's a console-against-the-wall install, not a coffee-table one. TOPTRO publishes no ratio, only the phrase "ultra short throw", so plan around 3 to 5 feet and verify once it's out of the box.

Here's the trick most shoppers miss. Measure your actual room before you shortlist anything. If your only clear wall is 5 feet from the seating, the 1.1:1 iSinbox needs the projector behind your head, and short throw stops being short.

When a different pick wins

Five if/then flips, each with a threshold you can check tonight.

• If the room has windows you can't cover, take the ViewSonic PS502W. 4,000 ANSI lumens is the only published brightness figure here that survives daylight.
• If your wall is under 4 feet from the nearest surface you can put a projector on, the Optoma's 10-inch claim or the ViewSonic's 0.5 ratio are your only realistic options.
• If you'll carry it more than once a week, the YQHS at 1.46 lb is the pick. Past about 4 lb, portable projectors quietly stop moving.
• If you want the projector to be the whole system with no HDMI stick, skip the ViewSonic. The other four all list built-in apps.
• If warranty length is the tiebreaker, ViewSonic's three years on parts and labour beats the two-year coverage from TOPTRO, iSinbox and YQHS, and doubles the Optoma's one year.

Screen size is the one threshold worth stating plainly. If you want past 100 inches, ViewSonic is the only listing here that publishes a maximum, at 150 inches.

The verdict

Three tiers, and the choice is cleaner than the spec sheets suggest.

At the entry end, the YQHS is the best short throw projector for swimmers if the budget is the binding constraint. 1.46 lb, a 0.65:1 claimed ratio and a two-year warranty for the lowest price position here is a genuinely good trade, provided you accept 350 lumens and a dark room. The iSinbox sits just above it and buys you a published 100-inch-at-7.9-feet figure plus 24 months of coverage.

In the middle, the TOPTRO Portable Smart Projector wins overall. 2.64 lb, a 5.55 x 7.63 x 6.22 in body, Google TV 14.0 and a 2-year warranty make it the pick that does the most jobs adequately without a caveat you have to design your room around.

At the premium end the answer depends on what you're buying. The ViewSonic PS502W is the better premium purchase for most people: 4,000 ANSI lumens, a 0.5 throw ratio, a 100-inch picture from 4.5 feet, three years of parts and labour. Its exact advantage over the TOPTRO is brightness, and it's the only listing here that quantifies it. The Optoma costs more, publishes less, and covers you for one year. Buy it for the 2.56-inch profile and the triple-laser engine, not for the specification sheet.

FAQ

Is a short throw projector worth it over a standard one?

A short throw projector is worth it when your room forces the issue. The ViewSonic PS502W puts a 100-inch image up from 4.5 feet; a standard projector needs roughly twice that. If you have 12 feet of clear space behind the seating, you don't need short throw. If your only clear wall is across a small living room, it's the only design that works.

Which offers better value, the YQHS or the iSinbox?

Better value depends on how far your wall is. The YQHS is the cheapest pick and the lightest at 1.46 lb, with a shorter 0.65:1 claimed ratio. The iSinbox costs a little more but publishes a full distance figure, 100 inches from 7.9 feet, and weighs 4.25 lb. For tight rooms and travel, YQHS. For a fixed living-room setup with real numbers behind it, iSinbox.

How many lumens do I need for the best short throw projector for swimmers?

The lumens you need track your light, not the water. The ViewSonic's 4,000 ANSI lumens handles moderate ambient light per the listing. The YQHS states 350 lumens, which needs darkness. Outdoors after dusk, the lower figures are usable. Before sunset or in a bright room, only the ViewSonic publishes a number that suggests it will hold up.

What's the difference between the TOPTRO and the ViewSonic PS502W?

The difference between the TOPTRO and the ViewSonic is portability against brightness. TOPTRO weighs 2.64 lb, runs Google TV 14.0 with built-in apps, and outputs 1080p. ViewSonic weighs 6.3 lb, publishes 4,000 ANSI lumens and a 0.5 throw ratio, but runs WXGA 1280x800 with no streaming platform. Dark room and mobility, take the TOPTRO. Lit room, take the ViewSonic.

Do 4K claims on these projectors mean a 4K picture?

The 4K claims here mean 4K input support, not 4K output. TOPTRO is refreshingly clear about it: the unit reads 4K content and displays it at 1080p. iSinbox and YQHS describe native 1080p with 4K compatibility. Four of the five picks are 1080p and the ViewSonic is WXGA 1280x800. Treat "4K support" in this category as a file-compatibility note.

Measure the distance from your wall to the nearest surface a projector can sit on, then pick from that number. Under 4 feet and the ViewSonic or the Optoma are your candidates. Around 5 feet and the TOPTRO or YQHS fit. Nearer 8 feet and the iSinbox is fine. The reason the TOPTRO is the right default isn't any single specification: it's that at 2.64 lb with a smart platform and two years of coverage, it's the one pick here that won't need replacing when your room changes.
