When you’d use this tool
Frame planning is constant work for any wall art seller. These are the four scenarios where I reach for this tool most:
- Sizing a custom commission to fit a specific frame the buyer owns. A buyer says "I have an 11×14 frame at home" — you compute 3,300 × 4,200 pixels at 300 DPI, check your source has enough resolution, and ship without surprises.
- Auditing your existing listings for sharpness. Old listings often have files sized for one frame but advertised as compatible with several. The finder lets you spot-check whether your file actually meets 300 DPI for every frame size you list.
- Planning a 5-ratio bundle. Most successful Etsy wall art listings include 5 size variants (4×6, 8×10, 11×14, 16×20, 24×36 typically). Use the finder to confirm your master image supports the largest variant before you commit.
- Quoting a non-standard frame request. Buyers occasionally request odd sizes — 14×18, 22×28, 30×40 — that don't match standard ratios. The finder shows whether the closest standard ratio is close enough to crop from, or if you need a dedicated file.
Common frame-sizing mistakes
Five frame mistakes that account for most "my print didn't fit" support tickets I've seen.
1. Sizing to outer frame dimensions instead of photo opening
A "10×12 frame" usually has an 8×10 photo opening — the extra 2 inches is the mat and frame width. Always size your file to match the printed area, never the outer frame.
2. Forcing an image into a non-matching ratio
An 8×10 (4:5) image stretched to fit 11×14 (≈1:1.27) will look distorted. Either crop the image to the new ratio (losing some content) or design separately for each ratio. Never stretch.
3. Adding mat space inside the digital file
The mat is a physical piece of paper the buyer adds, not part of your file. If you include white border space in the file expecting it to function as a mat, the buyer's mat will overlap and crop your image awkwardly.
4. Mixing US and ISO frame sizes
A US 16×20 frame is not the same as an A2 (16.5×23.4 inches). If a buyer asks for "an A2 print", don't ship a 16×20 file. Use the finder to verify which standard the buyer's frame uses.
5. Forgetting frame size affects required upscaling
A source image that comfortably prints at 8×10 (7.2 MP needed) falls short for 24×36 (78 MP needed) by a factor of 11. The same image needs aggressive AI upscaling for the bigger frame. Plan upscaling around your largest target frame, not your smallest.
