What size should images be for digital signage?
Quick answer: DigitalSignage.com's rule for signage images is to make every image exactly the pixel size of the screen or zone it fills: 1920 x 1080 for a landscape 1080p screen, 1080 x 1920 for portrait, 3840 x 2160 for 4K, and the zone's own width and height for a multi-zone layout. DPI does not matter on a screen; only pixels do. Save photos as JPEG at 85 to 90 percent quality (under 500 KB at 1080p, under 2 MB at 4K) and logos or text graphics as PNG. A video wall image is the combined size of the wall: 3840 x 2160 for a 2 x 2 wall of 1080p panels.
Key facts
- A full-screen 1080p image is 1920 x 1080 pixels (2.07 megapixels), and a 4K image is 3840 x 2160 pixels (8.29 megapixels), exactly 4 times as many.
- A portrait image is the same resolution rotated: 1080 x 1920 for 1080p and 2160 x 3840 for 4K.
- DPI or PPI metadata in an image file has no effect on a screen: a 1920 x 1080 image saved at 72 DPI and at 300 DPI looks identical on a display.
- Our image optimization guide targets JPEG photos under 500 KB at 1920 x 1080 and under 2 MB at 3840 x 2160, and the scene editor documentation recommends keeping every image under 10 MB.
- A 2 x 2 video wall of 1080p panels needs a 3840 x 2160 image, and a 3 x 3 wall needs 5760 x 3240 (18.66 megapixels).
- In an L-bar layout on a 1080p screen, the main zone is 1440 x 810, the sidebar 480 x 810 and the ticker strip 1920 x 270.

What resolution should a digital signage image be?
A digital signage image should match the native resolution of the screen, or of the zone, it fills, pixel for pixel. When the image is smaller, the player scales it up and edges go soft; when it is larger, the player scales it down and you pay in upload time, storage and memory for pixels nobody sees.
| Screen or canvas | Orientation | Image size in pixels | Megapixels | Aspect ratio |
|---|---|---|---|---|
| 720p HD | Landscape | 1280 x 720 | 0.92 | 16:9 |
| 1080p Full HD | Landscape | 1920 x 1080 | 2.07 | 16:9 |
| 1080p Full HD | Portrait | 1080 x 1920 | 2.07 | 9:16 |
| 4K UHD | Landscape | 3840 x 2160 | 8.29 | 16:9 |
| 4K UHD | Portrait | 2160 x 3840 | 8.29 | 9:16 |
| Square panel | Either | 1080 x 1080 | 1.17 | 1:1 |
| Ultrawide or stretched bar | Landscape | 3840 x 1080 | 4.15 | 32:9 |
| 2 x 2 wall of 1080p panels | Landscape | 3840 x 2160 | 8.29 | 16:9 |
| 3 x 3 wall of 1080p panels | Landscape | 5760 x 3240 | 18.66 | 16:9 |
| 2 x 2 wall of 4K panels | Landscape | 7680 x 4320 | 33.18 | 16:9 |
Bottom line: 1920 x 1080 covers most screens in 2026, 3840 x 2160 covers 4K panels and 2 x 2 walls of 1080p panels, and portrait is the same numbers swapped.
The native resolution of a screen is the fixed grid of physical pixels in the panel. You find it on the spec sheet, not in the TV's input menu. A 4K panel that is fed a 1080p signal still has 3840 x 2160 pixels; it simply scales the picture up. That is why a player's output resolution, the scene resolution and the image size should all agree with the panel. The full background on panel resolutions is in our screen resolution standards.
Most commercial and consumer displays sold for signage are 16:9. When a screen is mounted vertically it becomes 9:16, and the image must be made tall rather than rotated sideways. A landscape image dropped onto a portrait screen either fills only about a third of the height or is cropped hard, so portrait screens deserve portrait artwork from the start.
Does DPI matter for digital signage images?
No. DPI (dots per inch) and PPI (pixels per inch) stored in an image file are a printing instruction that tells a printer how large to print the pixels. A screen ignores that number completely and maps one image pixel to one screen pixel, so only the pixel dimensions count.
Here is the test anyone can run: export the same 1920 x 1080 photo twice, once tagged 72 DPI and once tagged 300 DPI. The files have the same pixel count, the same visible detail and almost the same file size, and on a 55-inch 1080p display they look identical. The 300 DPI version would only print smaller on paper.
What does vary between screens is the physical size of each pixel, which is the panel's own pixel density. A 55-inch 1080p display has about 40 pixels per inch, while a 55-inch 4K display has about 80. That density is a property of the hardware, not of your file, and it decides how large text looks at a given point size. Our typography and viewing distance guide turns that into font sizes.
Designers moving from print often ask for "300 DPI artwork". For signage, translate that request into "3840 x 2160 pixels for a 4K screen" or "1920 x 1080 for 1080p". Asking a print shop for an A3 file at 300 DPI gives you about 3508 x 4961 pixels, far more than any single signage screen can show.
What size should each zone image be in a multi-zone layout?
Each zone image should be the exact pixel width and height of its zone. A zone is an independent area of the screen with its own content, so an image built for the full screen and squeezed into a half-screen zone is either distorted, letterboxed or cropped, depending on the fit mode.
| Layout on a 1920 x 1080 canvas | Zone | Position (x, y) | Image size (1080p) | Image size (4K) |
|---|---|---|---|---|
| Full screen | Main | 0, 0 | 1920 x 1080 | 3840 x 2160 |
| Half and half | Left half | 0, 0 | 960 x 1080 | 1920 x 2160 |
| Half and half | Right half | 960, 0 | 960 x 1080 | 1920 x 2160 |
| L-bar | Main zone | 0, 0 | 1440 x 810 | 2880 x 1620 |
| L-bar | Sidebar | 1440, 0 | 480 x 810 | 960 x 1620 |
| L-bar | Ticker strip | 0, 810 | 1920 x 270 | 3840 x 540 |
| Main with bottom ticker | Main | 0, 0 | 1920 x 960 | 3840 x 1920 |
| Main with bottom ticker | Ticker | 0, 960 | 1920 x 120 | 3840 x 240 |
| Three-column menu | Header | 0, 0 | 1920 x 180 | 3840 x 360 |
| Three-column menu | Each column | 0, 640 or 1280 on x; 180 on y | 640 x 900 | 1280 x 1800 |
| Two-by-two grid | Each tile | 0 or 960 on x; 0 or 540 on y | 960 x 540 | 1920 x 1080 |
Bottom line: read the zone's width and height in pixels and export the image at exactly that size; on a 4K canvas every number doubles.
The L-bar main zone of 1440 x 810 is exactly 16:9, which is why a normal 16:9 video or photo fills it without bars. The sidebar at 480 x 810 is a tall 16:27 shape, so content for it must be designed as a narrow column, not cut from a landscape photo. The full set of documented layouts, with positions, is in screen layouts, zones and templates in SignStudio.
A ticker strip is the thin band along the bottom of the screen that carries scrolling headlines, a clock or the weather. If you supply a background image for it, make it 1920 x 120 or 1920 x 270 to match the strip, and remember that text inside a 120-pixel strip can only be about 70 pixels tall, which reads from roughly 15 feet.
Which file format and file size should signage images use?
Use JPEG for photographs and PNG for logos, text graphics, screenshots and anything with transparency. JPEG at 85 to 90 percent quality is visually clean on a wall screen and a fraction of the size of a PNG photo, while PNG keeps sharp edges on type and flat colour that JPEG would smear.
| Image type | Format | 720p target | 1080p target | 4K target | Why |
|---|---|---|---|---|---|
| Photograph, full screen | JPEG, quality 85 to 90 | Under 200 KB | Under 500 KB | Under 2 MB | Smooth gradients compress well |
| Graphic with flat colour and text | PNG | Under 500 KB | Under 1.5 MB | Under 5 MB | No compression artifacts on edges |
| Logo or overlay with transparency | PNG | Small, sized to the logo | Small, sized to the logo | Small, sized to the logo | JPEG has no transparency |
| Web-sourced image | WebP accepted, JPEG safer | Same as JPEG | Same as JPEG | Same as JPEG | Smaller files on modern players |
| Avoid | BMP, TIFF, oversized PNG photos | Huge files, no benefit on screen |
Bottom line: a full-screen 1080p photo should be a JPEG under 500 KB and a 4K photo under 2 MB; PNG is for graphics, not photos.
The targets come from our image optimization guide, and the format advice matches the digital signage file formats guide. A raw, uncompressed 1080p frame holds 6.2 MB of colour data and a 4K frame 24.9 MB, so a well-compressed JPEG at 500 KB or 2 MB is about one twelfth of the raw size, with no visible loss at viewing distance.
Small files matter for three reasons. They upload faster from the office, they download faster to every player, and they use less of the account's cloud storage. A player also has to decode every image into memory before it can show it, so a 6,000-pixel phone photo sent to a $40 stick is a common cause of slow slide changes.
Should you upscale images or design at 2x for retina screens?
Design at the screen's native resolution and do not double it "for retina". The retina idea comes from phones and laptops, where software draws at 2x and the operating system scales the interface. A signage player draws the image straight to the panel, so a 3840 x 2160 image on a 1080p screen is simply scaled down, wasting four times the pixels.
Upscaling runs the other way and is the more common problem. A 1280 x 720 image stretched to 1920 x 1080 is enlarged 1.5 times; on 4K it is enlarged 3 times and looks visibly soft, especially on text. Scaling one step between 1080p and 4K is acceptable for photos, because the factor is a clean 2 and viewers stand several feet away.
The practical rule: keep a master at the largest size you might need, usually 3840 x 2160, and export each screen's copy at its native size. If a source image is too small, replace it rather than enlarging it; AI upscalers can rescue a photo, but text and logos should always be redrawn from vector files.
One fair exception is a mixed fleet where the same playlist goes to 1080p and 4K screens. Then a single 3840 x 2160 image is a sensible compromise: the 4K screens show it natively and the 1080p screens scale it down by exactly half, which costs storage but never sharpness.
Worked example: images for a 3-zone menu board
The menu board below runs on a 55-inch 1080p display, landscape, with three zones: a menu list, a promotional photo and a ticker. Every number is computed, so the images can be exported once and never resized by the player.
| Step | Calculation | Result |
|---|---|---|
| 1. Canvas | Native 1080p panel | 1920 x 1080 scene |
| 2. Zone A, menu list | Left two thirds of the width, above the ticker | 1280 x 960 at 0, 0 |
| 3. Zone B, promo photo | 1920 minus 1280 = 640 wide, same height | 640 x 960 at 1280, 0 |
| 4. Zone C, ticker | Full width, 1080 minus 960 = 120 tall | 1920 x 120 at 0, 960 |
| 5. Check the sums | 1280 + 640 = 1920 and 960 + 120 = 1080 | No gaps or overlaps |
| 6. Zone B shape | 640 / 960 = 0.667 | A 2:3 portrait shape, so shoot or crop the food photo tall |
| 7. Zone B file target | 640 x 960 = 614,400 pixels, 29.6 percent of the screen's 2,073,600; 29.6 percent of 500 KB | JPEG under about 150 KB |
| 8. Zone A background target | 1280 x 960 = 1,228,800 pixels, 59.3 percent of the screen; 59.3 percent of 500 KB | JPEG under about 300 KB |
| 9. Physical size of Zone B | 55-inch 1080p is about 40 pixels per inch; 640 / 40 and 960 / 40 | 16 x 24 inches on the wall |
| 10. 4K version | Double every value | 2560 x 1920, 1280 x 1920 and 3840 x 240 |
Bottom line: three images at 1280 x 960, 640 x 960 and 1920 x 120 fill this menu board exactly, and the whole set is well under 1 MB.
Two things stand out. First, the promo photo is portrait even though the screen is landscape, so a landscape stock photo would need cropping to 2:3 before export, not after. Second, the zone images are smaller than a full-screen image, so their file budgets shrink in proportion to their pixel count; that keeps a menu board with a dozen rotating promos well inside the free plan's storage.
If the menu list is text from a Google Sheet rather than an image, Zone A only needs a background image, and the text is drawn live by the player at full sharpness. Our digital menu boards guide covers the content side.
How to do this in DigitalSignage.com
In SignStudio, create the scene at the screen's native resolution using the presets: HD 1920 x 1080, 4K UHD 3840 x 2160, Portrait HD 1080 x 1920, Square 1080 x 1080, Ultrawide 3840 x 1080, or a custom size for a video wall. Add zones and type exact X, Y, width and height values in the properties panel so each zone has a known pixel size, then export images to those sizes.
- Open SignStudio and create a scene with the preset that matches the panel.
- Add a playlist or image component for each zone and enter its exact position and size in pixels.
- Export each image at that zone size: JPEG for photos, PNG for graphics and transparency.
- Upload the files in Resources. The Image component accepts JPG, PNG, GIF, WebP and SVG.
- Set the Image component's fit mode (contain, cover, stretch or center) to cover or contain, never stretch, for a file that is not the zone's exact shape.
- Assign the scene to a screen and check it at the real viewing distance.
Storage is 1 GB on the free plan, 3 GB on mediaCLOUD Plus+ and 25 GB on Enterprise, and the scene editor documentation recommends keeping each image under 10 MB. Our documentation does not state whether SignStudio recompresses or resizes images on upload, so resize before you upload; for a definite answer ask support (support@digitalsignage.com, live chat at https://chat.digitalsignage.com/). Upload steps are in upload, organize and replace media in SignStudio.
Frequently asked questions
What size should images be for digital signage?
Make each image the exact pixel size of the screen or zone it fills: 1920 x 1080 for a landscape 1080p screen, 1080 x 1920 for portrait, 3840 x 2160 for 4K, and the zone's own width and height in a multi-zone layout. Save photos as JPEG at 85 to 90 percent quality, under 500 KB at 1080p and under 2 MB at 4K, and logos or text graphics as PNG.
What is the best image size for a 1080p TV screen?
1920 x 1080 pixels for a landscape screen and 1080 x 1920 for a portrait one. That is the panel's native grid, so the player shows the image pixel for pixel with no scaling. A full-screen JPEG photo at that size should be under about 500 KB.
Does DPI matter for digital signage?
No. DPI is a printing setting stored in the file and screens ignore it. A 1920 x 1080 image tagged 72 DPI and the same image tagged 300 DPI look identical on a display, because only the pixel dimensions count. Ask designers for pixel sizes, not DPI.
What size image do I need for a portrait digital sign?
1080 x 1920 pixels for a 1080p portrait screen and 2160 x 3840 for a 4K portrait screen. Design the artwork tall from the start; rotating or cropping a landscape image to fit a vertical screen loses most of the picture or leaves large bars.
What image size do I need for a 2 x 2 video wall?
The combined resolution of the wall: 3840 x 2160 for four 1080p panels, which is the same as one 4K frame, and 7680 x 4320 for four 4K panels. A 3 x 3 wall of 1080p panels needs 5760 x 3240. Keep text away from the seams where the bezels meet.
Should I use JPEG or PNG for digital signage?
JPEG at 85 to 90 percent quality for photographs and PNG for logos, text graphics, screenshots and anything with transparency. A PNG photo is several times larger than a JPEG with no visible benefit on a wall screen, while JPEG smears sharp text edges that PNG keeps clean.
Can I use a 4K image on a 1080p screen?
Yes, the player scales it down by half and it looks sharp, but the file is about four times larger than it needs to be, which costs upload time, storage and player memory. It is a sensible choice only when the same playlist also runs on 4K screens.
Which image size works on the TV I have?
Look up the TV's native resolution on its spec sheet or model page: most TVs from 43 inches up are 3840 x 2160, and many smaller or older ones are 1920 x 1080. Make images at that size, set the player's output to the same resolution, and turn off overscan with the picture size setting called Just Scan, Screen Fit, Full Pixel or 1:1.
