Pixels vs inches: printing a 24×36 poster

24×36 pixels is a tiny icon — useful for a small portrait sprite or a thumbnail marker, and nothing else. If that is what you need, the tool above is already set to it.

24×36 inches is a standard large poster, 2:3 portrait. To print it, the pixel size depends on the resolution you want:

300 DPI (close-up quality): 7200×10800 pixels
150 DPI (good for posters viewed from a metre or more): 3600×5400 pixels
100 DPI (acceptable from across a room): 2400×3600 pixels

Type the numbers for your chosen DPI into the width and height boxes above. Posters are viewed from a distance, so 150 DPI is a common, practical target.

Do not upscale a small photo to poster size. Enlarging a 1200-pixel image to 3600 does not add detail; it prints soft. Use the biggest original you have.

Check the shape. 24×36 is 2:3, the same as vertical camera photos. Phone photos are 3:4 and need trimming — use the cropper at 2:3 first.

Smaller 2:3 sizes: 600×900, 400×600. Print squares: 2400×2400.

Frequently asked questions

How many pixels do I need to print a 24×36 inch poster?

7200×10800 pixels at 300 DPI, 3600×5400 at 150 DPI, or 2400×3600 at 100 DPI. Posters are viewed from a distance, so 150 DPI is usually enough and keeps the file manageable.

What aspect ratio is 24×36?

24×36 has a portrait 2:3 aspect ratio. Any size with the same ratio — for example 12×18, 28×28 — can be scaled to it without cropping.

How big will a 24×36 image print?

At 300 DPI (photo quality) 24×36 prints at 0.08×0.12 inches (0.2×0.3 cm). At 150 DPI it covers 0.16×0.24 inches, fine for posters seen from further away.

How large is a 24×36 file?

A photo at 24×36 is usually 0 KB–0 KB as a JPG, and about 0 KB–0 KB as WebP. If you need it smaller, run it through the compressor afterwards.

Will my photo lose quality at 24×36?

No — a normal phone photo is much larger, so it is scaled down and stays sharp.

Can I resize to 24×36 without cropping?

Yes. Tick “Keep aspect ratio”: the whole picture is kept, but one side may come out shorter than 24×36. Without it, the image fills 24×36 exactly and the edges that do not fit the 2:3 shape are trimmed.

Are my images uploaded?

No. Resizing happens entirely in your browser. Nothing is transmitted or stored, and you can disconnect from the internet after the page loads and it still works.
