What Size Should You Print a Photo Collage? 8×10 to Poster
The one DPI rule you need, which frame sizes fit a 7:5 collage without cropping, and what to do about 8×10. Short, practical, no printer jargon.
The short version: for a desk frame, print 5×7. For a wall, 14×10. The rule of thumb is 150–300 DPI: divide your image’s pixel width by the print width in inches, and if the result is above 150 you’re safe — above 250 it’s sharp even up close.
The only math you need
DPI (dots per inch) = pixels ÷ inches. A 2800-pixel-wide image printed 14 inches wide is 200 DPI. That’s it. Everything else printers tell you is upsell.
300+ DPI: gallery sharp, survives being held and inspected.
200–300 DPI: excellent for framed prints viewed at normal distance.
150–200 DPI: fine for posters — nobody reads a wall from 10 cm.
Under 150 DPI: visibly soft. Print smaller or get a bigger file.
Applied to a “Do It For Her” collage
The generator’s collage is a 7:5 ratio. Sizes with zero cropping: 5×7, 10×7, 14×10, 21×15 inches.
The HD export is 2800×2000 pixels. That gives you ~400 DPI at 5×7 (overkill, in the best way), ~300 at 9×7, ~200 at 14×10, ~150 at 18×13. So: desk frame to mid-size poster, all covered by one file.
What about 8×10 and other standard frames?
8×10 is a 4:5 ratio — squarer than the collage. Don’t let the print shop “fill” the frame; it’ll crop the tape and borders off the edges. Order “fit” with white margins instead, or use a mat. A matted print looks more deliberate anyway — frame shops have charged extra for that look forever.
Paper, quickly
Matte: suits this template’s craft-paper frame, no glare under lamps. Default choice.
Glossy: punchier colors, but reflections and fingerprints.
Canvas: only for large wall pieces — see the poster guide.
Make the collage first, decide the size after — it’s free and takes five minutes in the generator.
