Resize a Photo to 12×18 Without Cropping
12×18 inches = 3,600 × 5,400 px at 300 DPI, or 1,800 × 2,700 px for a print viewed from a step away (150 DPI).
12×18 is the small poster: big enough to hang on its own, small enough not to need a frame shop. It's a 2:3 shape, the same as a 4×6 print. Upload your photo below and we'll extend the scene to 12×18 instead of trimming the sides off.

Why 12×18 Cuts Things Off
12×18 is exactly three times a 4×6 on each side, so it shares the 2:3 shape of camera photos, 4×6 prints and the 24×36 poster. A camera photo goes straight in with nothing lost. A 3:4 phone photo is proportionally wider and loses about a ninth of its width to fit. It's also the poster that fits on 13×19 paper with a half-inch border, which is why so many photo printers offer it. At 300 DPI it's 3,600×5,400 pixels, which we deliver at about 3,265×4,898, around 270 pixels per inch and sharp at arm's length.
Instead of trimming your photo down to the shape, we generate more of the scene around it until it fits — and sharpen the whole image in the same pass.
Where 12×18 shows up
- Small posters for a desk wall, studio or dorm
- Art prints and photo prints on 13×19 paper with a border
- Event posters and shop-window displays
- Enlargements of photos that already fit a 4×6
Pixels a 12×18 print needs
- Sharp in your hand (300 DPI)
- 3,600 × 5,400 px
- Sharp on a wall (150 DPI)
- 1,800 × 2,700 px
A smaller photo still prints, just softer. Check yours against every size on the print size chart. Changing the DPI setting alone doesn’t add pixels: how to convert an image to 300 DPI.
12×18 Questions

3,600×5,400 for 300 DPI, or 1,800×2,700 at 150 DPI, fine from a step away. We deliver about 3,265×4,898, comfortably sharp for a poster this size.
