Sizes from the Walgreens Photo poster page, October 2026; custom sizes are also offered. Check the store for same-day pickup on the size you want.
Materials are satin photo paper, paper board (a rigid styrene backing that needs no frame), and adhesive poster prints for walls and windows. The size choice matters more than the material for how the photo looks: it decides what gets cropped and how sharp it prints.
Why a Walgreens poster comes out cropped
Each size has a fixed shape, and a photo that doesn’t match it is enlarged until it fills the paper, with the overflow trimmed off. A phone photo is 3:4, so it fits 18×24 exactly. At 12×18, 20×30 or 24×36 it loses about a ninth of its width; at 16×20 and 11×14, a sliver of its height. A camera photo is the opposite: perfect at the 2:3 sizes, cropped at 18×24.
- Pick the size that matches your photo when you can. For a phone photo, that is 18×24.
- When you need a particular size, extend the photo to that shape first, using the size links in the table, so the upload has nothing to trim.
- Look at the crop preview before you pay. It shows what will be cut; if it’s a face or a name, fix the photo rather than nudging the frame.
Will it be sharp enough?
Posters are seen from a few feet away, where 150 pixels per inch looks sharp; the large-format guide explains why. A 12-megapixel phone photo (3,024 × 4,032) is about 168 DPI at 18×24 and 126 at 24×36: fine for the first, a little soft up close for the second.
Photos saved from Facebook, Instagram or a text message are much smaller and print soft at any poster size. Use the original from the camera roll, or upscale it to the poster size before uploading.
