A lower pixel pitch is better only when people will stand close to the screen. Pixel pitch is the distance in millimetres between neighbouring LEDs; the rule of thumb is one metre of minimum viewing distance per millimetre of pitch. Pick the largest pitch your closest viewer will not notice; each step down adds cost, pixels and processing.

Key takeaways
- Lower pitch means more LEDs per module, so a sharper image at close range. It does not make a screen better from a distance.
- The datasheet minimum viewing distance for Dynamo’s DRA range is 1.29 m at 1.29 mm, 1.93 m at 1.93 mm and 2.58 m at 2.58 mm.
- Resolution comes from the module: a 496 mm DRE cabinet is 384 × 384 pixels at 1.29 mm, 256 × 256 at 1.93 mm and 192 × 192 at 2.58 mm.
- Every step down in pitch raises price per square metre and the pixel count your processor and content have to drive.
- Dynamo installs run from 0.93 mm meeting-room walls to 3.9 mm foyer screens; the project decides the pitch, not the other way round.
What pixel pitch means
Pixel pitch is the distance from the centre of one LED pixel to the centre of the next, measured in millimetres. A 1.9 mm screen has its pixels 1.9 mm apart; a 3.9 mm screen has them 3.9 mm apart. The term is the LED industry’s version of dot pitch on older monitors, and it is the single number that most affects how close a viewer can stand.
The easy way to picture it is the television comparison. A 55-inch HD set and a 55-inch 4K set are the same size, but the 4K set packs four times as many pixels into the same panel, so its pixels are closer together and the picture holds up when you sit nearer. An LED wall works the same way: a lower pitch is the “4K” version of the same wall size.
Is a higher or lower pixel pitch better?
Neither is better on its own. A lower pitch is better when the audience is close: a boardroom, a shop window, a gallery plinth, a reception desk. A higher pitch is better when the audience is far away and the budget has to stretch across a large area: a foyer screen viewed from a mezzanine, an outdoor wall, a stage backdrop. The mistake is to treat pitch as a quality score. It is a distance setting, and the right one is the largest pitch your closest viewer will not notice.
Our viewing distance and pixel pitch guide works through the arithmetic; the short version follows below, with the datasheet figures for each Dynamo range.
Pixel pitch, resolution and viewing distance
Resolution comes from the module, not the pitch
An LED wall’s resolution is the number of pixels on each module multiplied by the number of modules, never the wall width divided by the pitch. A DRE Series cabinet is 496 mm square and made of four 248 mm modules. At 1.29 mm each module is 192 × 192 pixels, so the cabinet is 384 × 384; at 1.93 mm the cabinet is 256 × 256; at 2.58 mm it is 192 × 192. A wall six cabinets wide and three high (2.98 m × 1.49 m) therefore gives 1,536 × 768 pixels at 1.93 mm but 2,304 × 1,152 at 1.29 mm. Same wall, twice the pixels, and a processor and content pipeline that have to keep up. Our guide to native resolution and content scaling explains why that matters.
The one-metre-per-millimetre rule
The working rule is that the minimum comfortable viewing distance in metres roughly equals the pitch in millimetres. Dynamo’s DRA specification states it directly: a minimum viewing distance of more than 1.29 m for the 1.29 mm cabinet, 1.55 m for 1.55 mm, 1.93 m for 1.93 mm and 2.58 m for 2.58 mm. The rule comes from normal visual acuity: beyond that distance the eye can no longer resolve the gap between LEDs and the picture reads as continuous. Stand closer and the dots show; stand further away and you have paid for pixels nobody can see.
Dynamo ranges by pixel pitch
The table lists the pitches Dynamo installs most often, with the module or cabinet pixel counts from each datasheet. Viewing distances are the datasheet figure where one is stated and the rule of thumb where it is not.
| Pixel pitch | Dynamo range | Module / cabinet | Pixels per module / cabinet | Minimum viewing distance |
|---|---|---|---|---|
| 0.93 mm | DYF Series (flip-chip COB) | 300 × 337.5 mm module | 320 × 360 | ≈ 1 m (rule of thumb) |
| 1.25 mm | DYF Series (flip-chip COB) | 300 × 337.5 mm module | 240 × 270 | ≈ 1.25 m (rule of thumb) |
| 1.29 mm | DRA Series | 496 × 496 mm cabinet | 384 × 384 | > 1.29 m (datasheet) |
| 1.55 mm | DRA / DRE Series | 496 × 496 mm cabinet | 320 × 320 | > 1.55 m (datasheet) |
| 1.58 mm | DFC Series (flip-chip COB) | 304 × 342 mm module | 192 × 216 | ≈ 1.6 m (rule of thumb) |
| 1.93 mm | DRA / DRE Series | 496 × 496 mm cabinet | 256 × 256 | > 1.93 m (datasheet) |
| 2.58 mm | DRA / DRE Series | 496 × 496 mm cabinet | 192 × 192 | > 2.58 m (datasheet) |
| 2.9 mm | DX Series | 250 × 250 mm module | 84 × 84 | ≈ 3 m (rule of thumb) |
| 3.9 mm | DX Series | 250 × 250 mm module | 64 × 64 | ≈ 4 m (rule of thumb) |
Below about 1.5 mm the choice of LED package matters as much as the pitch. Flip-chip COB ranges such as DFC and DYF seal the diodes under a flat surface, which is why they are specified for close-view meeting rooms; the sub-1 mm decision guide covers when that extra step is worth it.
Text, graphics and the closest viewer
Content decides how strict you need to be. Full-screen video forgives a coarser pitch because the eye follows motion, not edges. Spreadsheets, CAD drawings, design proofs and small type do not: a designer reviewing artwork at 1.5 m on a 2.9 mm wall will see the pixel grid through every thin line. For that kind of work, specify from the closest realistic viewer and treat 1.9 mm as the coarsest sensible pitch, with 1.2 mm to 1.5 mm where people sit at a table in front of the screen.
What a lower pixel pitch costs you
Price per square metre
A lower pitch means more LEDs, more driver ICs and tighter manufacturing tolerances on every module, so the price per square metre rises with each step down. The exact step depends on the range, but it is never small, and on a large wall the difference between 1.9 mm and 2.6 mm can fund the processing, structure or installation that the project also needs.
Processing and content
More pixels need more sending capacity and more capable media servers. The 2,304 × 1,152 wall above is more than 2.6 million pixels; the same footprint at 2.58 mm is 1,152 × 576, a little over 660,000. Content has to be produced or rendered at the higher count too, or it will be scaled and the sharpness you paid for is lost. Budget for the pipeline, not just the panels.
Installation tolerance
The closer people stand, the more visible a misaligned cabinet or a brightness step between modules becomes. Fine-pitch walls need flatter mounting structures, more careful seam alignment and a proper calibration pass at commissioning. That is time on site, and it should be in the quote.
Lower pixel pitch in practice: Dynamo projects
1.9 mm immersive room for Pixel Artworks, London
At the Pixel Artworks Lighthouse in Farringdon, visitors walk right up to the walls of an immersive LED room with curved corners. Pixel Artworks chose a resin-protected 1.9 mm DRE Series for it: close enough viewing to justify fine pitch, with a surface that stands up to being touched.
0.93 mm 4K wall in a corporate meeting room
For a client’s meeting room at 45 Mortimer Street, Dynamo installed a native 4K (3,840 × 2,160) DYF Series wall at 0.93 mm, used for VR-style interactive walkthroughs viewed at close range. Sub-1 mm was the right call because the content was fine-detail interactive rendering viewed from a table, not video from across a foyer.
1.29 mm plinth panels for a gallery
For Botto’s Algorithmic Evolution exhibition at Verse, London, 22 single 496 mm DRE cabinets at 1.29 mm sat on plinths at eye level, each showing one artwork at 384 × 384 pixels. Visitors stand about a metre from a plinth, which is exactly the datasheet viewing distance for that pitch.
1.95 mm museum wall in Blackpool
The 15 m museum wall in Blackpool runs at 1.95 mm with a 7,936 × 1,024 pixel canvas. Visitors walk along it at a couple of metres, so 1.95 mm holds the historical photo collages cleanly without the cost of going finer across 15 m of width.
How to choose the right pixel pitch
- Measure the closest realistic viewing distance, not the average. The person at the front row or the reception desk sets the pitch.
- Decide what the content is. Video and graphics tolerate a coarser pitch; text, data and design proofs do not.
- Pick the largest pitch that passes both tests. Then check the module maths: cabinet pixels × cabinets across and down gives you the canvas your content team must design for.
- Cost the whole system. Panels, processing, structure, calibration and content production all scale with pixel count.
- Look at surface and package below 1.5 mm. Flip-chip COB and resin-protected modules matter more than the last 0.2 mm of pitch when people can touch the screen.
If the wall is a general-purpose display in a lobby or event space, Dynamo’s LED video walls page covers the standard fixed-install pitches; the full product range lists each series by pitch and use case.
Higher or lower pixel pitch: frequently asked questions
Is a lower pixel pitch better than a higher one?
Lower is better when viewers are close, higher is better when they are far away and the wall is large. The pitch in millimetres is roughly the minimum viewing distance in metres, so a 1.9 mm wall suits viewers from about 2 m and a 3.9 mm wall from about 4 m. Choose the largest pitch your nearest viewer will not notice and spend the saving on processing and installation.
What is a small pixel pitch LED display?
Small pitch, fine pitch and narrow pitch all describe LED screens with a pitch of roughly 2.5 mm or less, built for indoor viewing at a few metres or closer. Dynamo’s DRA, DRE, DFC and DYF ranges cover 0.93 mm to 2.58 mm. Below about 1.5 mm most projects move to flip-chip COB or resin-protected modules so the surface is flat, non-reflective and robust to touch.
Does a lower pixel pitch mean higher resolution?
For the same screen size, yes. Resolution is module pixels multiplied by module count, and a lower pitch puts more pixels on each module: a 496 mm DRE cabinet is 192 × 192 pixels at 2.58 mm and 384 × 384 at 1.29 mm. A wall of the same cabinets therefore has four times the pixels at 1.29 mm, and needs a processor and content sized to match.
Does a lower pixel pitch make text and detailed graphics easier to read?
Yes, at close range. Thin lines, small type and spreadsheets break up on a coarse pitch when viewed from a desk or a meeting table, which is why boardrooms and design studios specify 1.2 mm to 1.9 mm. From five metres or more the difference is invisible, so a foyer or auditorium screen showing the same content can use a larger pitch without anyone noticing.
What pixel pitch do I need for a meeting room or boardroom?
Most boardrooms sit people two to four metres from the wall, so 1.2 mm to 1.9 mm is the usual band. Go to the finer end if the screen will show spreadsheets, drawings or video calls with small faces, and to 1.9 mm if it is mainly presentations and video. Sub-1 mm is reserved for rooms where people sit within about a metre of the screen.
Is a lower pixel pitch always worth the extra cost?
No. Below the distance at which viewers can no longer see the pixels, a finer pitch adds cost, power and processing without any visible gain. It is worth it for close-view rooms, retail windows and galleries; it is wasted on a screen viewed from a mezzanine or across a car park. Match the pitch to the nearest viewer and put the budget into calibration and content instead.
