How many pixels your photo needs for a canvas, blanket, flag or pillow
Last updated October 15, 2026
The pixel counts a sharp print needs at common sizes, how to read them off your photo, what a phone picture can cover, and what the editor's quality readout means.
The rule
Multiply the print size in inches by the resolution you want. At 150 dpi, a working rule of thumb for photographs viewed from a step away, a 12 × 18 in print needs 1800 × 2700 pixels; at 300 dpi it needs twice that in each direction. Enlarging a small picture does not add detail, so when a photo falls short, choose a smaller size or start from a larger original.
For each size you pick, the editor shows the recommended pixels and rates your image against them (Advanced tools, then Print readouts). That readout is the authority for the product in front of you; the table below is for planning before you upload.
Pixels needed at 150 dpi
| Product and size | Pixels (width × height) |
|---|---|
| Canvas print, 8 × 10 in | 1200 × 1500 |
| Canvas print, 12 × 18 in | 1800 × 2700 |
| Canvas print, 16 × 20 in | 2400 × 3000 |
| Canvas print, 24 × 36 in | 3600 × 5400 |
| Pillow cover, 18 × 18 in | 2700 × 2700 |
| Garden flag, 12 × 18 in | 1800 × 2700 |
| House flag, 28 × 40 in | 4200 × 6000 |
| Blanket, 30 × 40 in | 4500 × 6000 |
| Blanket, 50 × 60 in | 7500 × 9000 |
| Blanket, 60 × 80 in | 9000 × 12000 |
What a phone photo covers
A 12-megapixel phone photo is about 3000 × 4000 pixels, which carries a 16 × 20 in canvas or an 18 in pillow at 150 dpi and a 30 × 40 in blanket at 100 dpi, where a soft fabric viewed from the sofa still looks right. Pictures sent through a messaging app are usually shrunk; use the original from the camera roll.
Uploads can be up to 100 MB and 80 megapixels, which is above the largest recommendation in the catalogue.
Reading your own photo
- On a phone, open the picture's details (the i button on iPhone, the three-dot menu on Android) to see its pixel size.
- On a computer, the file's properties or Get Info show the dimensions.
- Screenshots and web images are small; a screenshot of a photo is not the photo.
