What pixel size do I need for an 8×10 print?

8×10 inches at 300 DPI is 2400×3000 pixels. That same 4:5 file also prints 4×5 and 16×20, since they share the ratio — size the file for 16×20 (4800×6000) and it scales down cleanly.

How do I prepare a file for an 11×14 frame?

11×14 is its own ratio (11:14), so it needs its own file at 3300×4200 pixels for 300 DPI. An 8×10 (4:5) file won't fit an 11×14 frame without borders or cropping.

Should I make a separate file for every frame size?

No — prepare one file per ratio. 8×10 and 16×20 are both 4:5 and print from one file; 18×24 is 3:4; 24×36 is 2:3. Grouping by ratio means a few files cover every frame.

Can I enlarge a small image to fit a big frame?

It's risky. Enlarging adds pixels the image never had, so large prints look soft. Always start from the highest-resolution original and crop down to each size instead of scaling a small file up.

Why does my file print smaller than expected?

The DPI metadata is probably low (often 96 DPI from a design export). Set it to 300 DPI so the print shop sizes the file correctly, or run it through a tool that writes true 300 DPI density.

How to Prepare Print Files for Common Frame Sizes (8×10, 11×14, 16×20 & More)

Prep files that drop straight into the frames buyers actually own. Here's the ratio and exact 300 DPI pixel target for each popular size, and how to hit them.

Key takeaways

Each frame size belongs to a ratio: 8×10 and 16×20 are 4:5; 11×14 is its own 11:14; 18×24 is 3:4.
Prep by ratio, not by size — one 4:5 file covers 4×5, 8×10 and 16×20.
Pixel target = inches × 300: 8×10 → 2400×3000, 16×20 → 4800×6000, 18×24 → 5400×7200.
Always start from the highest-resolution original and crop down; never enlarge a small file to fit.

Preparing print files is two decisions: the right ratio for the frame, and enough pixels for 300 DPI. Here's exactly what each popular frame size needs, and the fastest way to hit it.

The common frames, by ratio and pixels

Frame size	Ratio	Pixels @ 300 DPI	Same-ratio sizes
8×10	4:5	2400×3000	4×5, 16×20
11×14	11:14	3300×4200	(its own shape)
16×20	4:5	4800×6000	4×5, 8×10
18×24	3:4	5400×7200	6×8, 9×12, 12×16
24×36	2:3	7200×10800	4×6, 8×12, 12×18
A4	ISO A	2480×3508	A5, A3, A2, A1

Step 1 — Group frames into ratios

Don't prep 8×10 and 16×20 separately — they're both 4:5, so one file covers both. Map every frame you want to serve to its ratio and you'll find you need just a handful of files.

Step 2 — Size the file for the largest frame in the ratio

Prepare each ratio at the pixel count of its biggest size. A 4:5 master at 4800×6000 (16×20) also prints a crisp 8×10 and 4×5 when scaled down. Downscaling keeps detail; upscaling invents it and looks soft.

Step 3 — Crop, don't stretch

Fit the image to the ratio by cropping to the frame's shape, never by squishing. Keep the important part of the art inside a central safe zone so no crop cuts it off.

Step 4 — Write 300 DPI into the file

Set the density metadata to 300 DPI so print shops read the right size. Many design tools (Canva PNGs especially) leave files at 96 DPI, which is the top cause of "why did it print small?"
