Choose the result before changing the file
If a face, signature or building sits near an edge, inspect that area before accepting an automatic crop. Filling the sheet and keeping every part of a differently shaped image cannot both happen without stretching or adding space. Stretching changes the subject’s proportions.
- Crop when you want the image to fill the paper and can remove some edges.
- Keep borders when the complete composition matters more than filling the sheet.
- Choose a matching paper ratio when its size also works for your frame.

How much does a 3:2 image lose?
Consider a landscape file measuring 6,000 × 4,000 pixels. Its width divided by height is 1.5, or 3:2. The table keeps the image in landscape orientation: a print commonly called 8×10 is entered as 10 inches wide and 8 high.
These are independent geometry examples, not a prediction for every photo. A 4,032 × 3,024 file has a 4:3 ratio; cropping that file to 5:4 keeps 3,780 × 3,024 pixels and removes only 6.25%. Enter your actual dimensions.

| Print proportions | Pixels kept | Image area removed | Centered loss at each side |
|---|---|---|---|
| 6 × 4 (3:2) | 6,000 × 4,000 | 0% | 0 pixels |
| 7 × 5 (7:5) | 5,600 × 4,000 | 6⅔% | 200 pixels |
| 10 × 8 (5:4) | 5,000 × 4,000 | 16⅔% | 500 pixels |
Keep the complete photo with borders
Fit that same complete image onto a 10 × 8 inch sheet. With no minimum border, the image measures 10 × 6⅔ inches. Centering leaves ⅔ inch above and below, and no side borders.
If you want at least ½ inch on every edge, the usable space is 9 × 7 inches. The largest uncropped image that fits is 9 × 6 inches, so the final borders are ½ inch left and right and 1 inch top and bottom. A minimum border is a lower limit; it does not promise four equal borders.
The paper size includes these borders. They are blank areas of the printed sheet, not a separate mat board. The calculator plans the dimensions; create the matching canvas or layout in your editor and check the print service’s preview.

Check the pixels left after cropping
The 10×8 crop leaves 5,000 × 4,000 pixels. Dividing each dimension by 300 PPI gives about 16.67 × 13.33 inches. Printing those pixels at 10 × 8 inches instead gives 500 PPI. These calculations describe pixel density, not a promise of sharpness; focus, compression, subject detail and viewing distance still matter.
Changing a PPI label does not recover a cropped subject. Use the cropped dimensions when planning physical size, and inspect the actual image rather than treating one resolution number as a quality verdict.

Check the final ordering preview
Moving a crop toward the left or right changes which content disappears, not the total loss for the same ratio. Keep the subject where you want it in your editor or the lab’s preview.
A matching ratio does not guarantee that the printer preserves the very last edge. Borderless printing can enlarge the image slightly; lab handling and paper movement can also affect the edge. Check the specific service or printer settings rather than applying a supposed universal allowance.
- Confirm paper orientation and the selected print size.
- Check whether the order uses fill/crop or a bordered layout.
- Keep essential text and faces clear of the edges shown in the final preview.
