Custom Aspect Ratios for Print Artists (11x14, 5x7, and Odd Sizes)
Preset 4:5 tools skip right past 11×14 and 5×7. Entering a custom width × height at 300 DPI is how odd frames actually get filled without stretching an Instagram ratio.
Direct answer
A custom aspect ratio just means entering the real frame size — 11×14, 5×7, 10×10, 12×36 — instead of forcing a 4:5 or 2:3 preset to do the job. The pixel size is width × 300 by height × 300 at 300 DPI: 11×14 works out to 3300×4200 pixels, and 5×7 comes to 1500×2100. Neither matches the common 4:5 or 2:3 presets, so a tool that only offers those will crop the wrong edges every time.
Marketplace crop apps default to social-media ratios because that's what phone cameras produce. But print artists sell frames from Target, IKEA, and custom moulding shops — 11×14 is everywhere in North America, and 50×70 cm is just as common across Europe. Neither one is a 4:5.
If your tool only offers 1:1, 4:5, and 9:16, you'll end up shipping the wrong crop and calling it "close enough." Buyers who just spent $40 on a frame will notice the difference.
Why presets miss real frames
11×14 isn't a 4:5 (forcing that ratio would give you 11.2×14, which you shouldn't do). 5×7 isn't a 2:3 either. Panoramas and square tiles are even further off. If your tool only offers Instagram-style ratios, you'll ship the wrong crop without realizing it.
Instead, enter the width and height directly, in inches, centimeters, or millimetres. The pixel size is simply the physical size × 300. Reopic Studio works entirely on custom ratios — there's no fake 4:5 grid getting in the way.

| Size | Ratio (approx.) | Pixels |

| 11 × 14 in | 11:14 | 3300 × 4200 |
| 10 × 10 in | 1:1 | 3000 × 3000 |
| 12 × 36 in panorama | 1:3 | 3600 × 10800 |
| 50 × 70 cm | 5:7 | 5906 × 8268 |
| A4 | ISO A | 2480 × 3508 |
Thinking in ratios without a calculator
Divide the long side by the short side: 14 ÷ 11 ≈ 1.27, versus 10 ÷ 8 = 1.25 for a 4:5. Close, but not equal — and on an 11×14, that 0.02 difference is either extra wall showing or a chopped chin. Always crop to the actual pair of numbers, not the nearest familiar ratio.
Keep one focal point so that 5×7 and 11×14 still frame the same subject. Then batch export whichever SKUs you actually sell — not whatever a competitor happens to list.
Metric frames and mixed shops
If you sell 8×10 to US buyers and 50×70 cm to EU buyers, both need a spot in your ratio list. Multiply centimetres by 300 ÷ 2.54 for pixels, or just enter cm directly in Reopic and let it handle the conversion.
Keep in mind that A4 is measured in millimetres while 11×14 is inches — mixing units in your head is exactly how 297 mm accidentally becomes 297 inches in a broken export. Stick to whatever unit is on the listing.
Exporting custom sizes in Studio
Open Studio, enter width × height in inches, cm, or mm, pin the subject, and Export Artwork. Free covers three custom ratios on one image per day. Pro is a one-time $33 for unlimited ratios and ZIP folders.
11×14 and 5×7 in practice
11×14 is the frame that sits right next to 8×10 on the shelf — but it isn't the same crop. Starting from a 4:5 painting, you'll lose a little off the long sides; starting from a 2:3 poster, you'll lose more. Always preview 11×14 before adding it as a variation off a 12×18 hero image.
5×7 tends to be a gift SKU. At 1500×2100 pixels, it's the most forgiving size on megapixels and the least forgiving on composition — there's simply not much room around a face. Pin the eyes carefully. If 5×7 clips a signature, either move the signature in the original art or skip that size for that piece.
Squares, panoramas, and "close enough"
10×10 and 12×12 are both 1:1. Forcing a 4:5 portrait into a square crops out hair or chin — a workable trade for a face-centric piece, a bad one for a full-figure painting. Don't auto-generate squares for every listing without checking first.
Panoramas (12×36, 10×30) need a genuinely wide original to work — you can't manufacture width from a 4:3 phone photo without stretching or leaving huge empty pads. If you didn't shoot or paint wide, skip the panorama SKU entirely. Focal-point cropping still earns its keep on a true wide file, keeping the interesting third of the frame in view as height changes.
Always write the real size in the filename — 11x14in, 50x70cm. When a VA uploads to Etsy, a file called "final_crop_3.jpg" is exactly how a 5×7 file ends up in an 11×14 SKU. Custom ratios only help if the export is actually labeled with the inches you typed.
FAQ: custom aspect ratio print
How many pixels is 11x14 at 300 DPI?+
3300×4200 pixels in portrait, or 4200×3300 in landscape.
How many pixels is 5x7 at 300 DPI?+
1500×2100 pixels in portrait.
Is 11x14 the same as 8x10?+
No. 8×10 is a 4:5 ratio, while 11×14 is 11:14 — you'll need two separate crops from the same focal point.
Can I crop 4:5 and pad to 11x14?+
Padding just adds borders that the frame will either hide or make look like a mat you never sold. Crop to 11×14 directly instead.
How do I convert centimetres to pixels at 300 DPI?+
Divide centimetres by 2.54 to get inches, then multiply by 300 — or just enter centimetres directly in Reopic and let it export. 50×70 cm comes out to about 5906×8268 pixels at 300 DPI.
