Make One Image Fit Every Frame Size (5 Crops)
How to turn a single artwork into files for every standard frame — the exact crop loss per ratio, focal-point strategy, and composition rules.
A buyer's frame is a fixed shape; your art is another. Since you can't control their frame, you ship five shapes of your art. The craft is in where each crop lands.
The real cost of each crop
Starting from a 2:3 source (the tallest common ratio), here's exactly how much image each target shape consumes, cropping height and keeping full width:
| Target ratio | Height kept | Height lost |
|---|---|---|
| ISO A (1:1.414) | 94.3% | 5.7% |
| 5:7 | 93.3% | 6.7% |
| 3:4 | 88.9% | 11.1% |
| 11:14 | 84.8% | 15.2% |
| 4:5 | 83.3% | 16.7% |
The 4:5 crop — the one that makes 8x10, your best-selling size — eats a sixth of a 2:3 composition. If your subject fills the frame edge to edge, that crop decapitates it.
Compose (or choose) with a safe zone
Rule that solves this before it exists: keep everything essential inside the central 80% of the long axis. Titles, faces, signatures, the tips of botanical stems — all inside the zone. The outer 10% on each end is "sacrifice space": sky, background wash, negative space. Art directed this way crops to all five ratios with zero pain.
For existing art that wasn't composed this way, the crop position has to move per ratio — centered for a symmetric mandala, shifted up for a portrait, shifted down for a landscape with a big sky. Batch tools that only center-crop fail here; you want a per-ratio draggable focal point, which is exactly what the Ratio-Pack Generator gives you: five live previews, drag each one, download the set.
Worked example: a moon-phase print, 4800x7200 px
Source is 2:3 with the moon sequence running vertically, lowest moon 400 px from the bottom edge.
- ISO A crop (keep 94.3% → 4800x6788): centered crop trims 206 px top and bottom — the bottom moon survives with 194 px to spare. Fine centered.
- 4:5 crop (keep 83.3% → 4800x6000): centered would trim 600 px from the bottom, slicing the lowest moon. Drag the focal point down so the bottom trim is only 250 px and the top absorbs 950 px of empty night sky. Composition saved.
- Final check: 4800 px wide ÷ 300 = 16 in, so promise "crisp to 16x20 / 16x24," per the pixels-to-inches chart.
Five files export in one click, each with 300 DPI metadata embedded, ZIP'd and named by size.
Then package it
Five ratio files is also exactly Etsy's per-listing file cap, which is convenient — see how many sizes to include for the listing-copy side, and the 20MB limit workaround if you sell the full per-size pack rather than ratio masters.
