PPI, fit and fill
PPI tells you how many image pixels land in each printed inch. Printer DPI describes printer dots, so it is not the same measurement. At 8 × 12 inches, a 2400 × 3600-pixel image is 300 PPI. Make the same image bigger and its pixels spread farther apart.
Fit keeps the whole image visible and may leave empty space. Fill covers the print area and trims some of the image when the aspect ratios differ. Check where faces, signatures and important details land before approving a crop.
Changing a file's resolution tag alone does not add image detail. Resampling can add pixels but cannot certify that missing detail has been recovered. A print's appearance also depends on source quality, paper, process, viewing distance and the selected product's rules. Use this calculator as a sizing estimate; use the product's template and proof for production decisions.
Worked examples
Every number below comes from the same arithmetic the calculator runs, with a 300 PPI reference. Sizes are numerical examples, not a list of InkFE trim sizes.
| Example | Effective PPI | Complete image at this scale | Margins or crop per edge | Area retained |
|---|---|---|---|---|
2400 × 3600 px at 8 × 12 in· A portrait photo whose 2:3 shape matches the print exactly. | ||||
| Fit the whole image | 300 PPI | 8 × 12 in | Margins: left/right 0 in, top/bottom 0 in | 100% |
| Fill the print area | 300 PPI | 8 × 12 in | Crop: left/right 0 px, top/bottom 0 px | 100% |
| Fit and fill agree because the shapes match: no margins, no crop. The same image at 203.2 × 304.8 mm gives the same result because the inputs are converted to inches first. | ||||
2400 × 3600 px at 8 × 10 in· The same photo on a slightly squarer print. The shapes no longer match, so fit and fill pull apart. | ||||
| Fit the whole image | 360 PPI | 6.67 × 10 in | Margins: left/right 0.67 in, top/bottom 0 in | 100% |
| Fill the print area | 300 PPI | 8 × 12 in | Crop: left/right 0 px, top/bottom 300 px | 83.33% |
| Fit keeps every pixel but leaves empty paper on the left and right. Fill uses the full width, which means the top and bottom of the image are trimmed. | ||||
3000 × 2000 px at 8 × 10 in· A landscape photo placed on a portrait print without rotating it. | ||||
| Fit the whole image | 375 PPI | 8 × 5.33 in | Margins: left/right 0 in, top/bottom 2.33 in | 100% |
| Fill the print area | 200 PPI | 15 × 10 in | Crop: left/right 700 px, top/bottom 0 px | 53.33% |
| Fill has to enlarge the image a lot to cover the tall print, so the PPI drops and almost half of the picture is cropped away. The calculator never rotates the print for you; use Swap print orientation to compare 10 × 8 explicitly. | ||||
2400 × 3600 px at 10 × 8 in (swapped)· The portrait photo after swapping the 8 × 10 print to landscape orientation. | ||||
| Fit the whole image | 450 PPI | 5.33 × 8 in | Margins: left/right 2.33 in, top/bottom 0 in | 100% |
| Fill the print area | 240 PPI | 10 × 15 in | Crop: left/right 0 px, top/bottom 840 px | 53.33% |
| Swapping raises the PPI in both modes, but fill now crops far more of the image. That trade-off is why orientation is your explicit choice rather than something the calculator picks silently. | ||||
2400 × 3600 px at a 150 PPI reference. Lower the reference to 150 PPI and the largest proportional print becomes 16 × 24 in, twice each side of the 300 PPI figure. That is a numerical reference for a print viewed from farther away, not certified sharpness.
How the estimate is calculated
Print sizes in centimeters or millimeters are converted to inches first (2.54 cm or 25.4 mm per inch). The image is scaled proportionally, so it is never stretched in one direction.
- Fit uses the smaller of the two scales (print width ÷ pixel width and print height ÷ pixel height). Whatever paper the image does not cover is split evenly into margins on opposite edges.
- Fill uses the larger scale. Whatever image falls outside the print is split evenly into a crop on opposite edges, counted in source pixels.
- Effective PPI is one divided by the inches each source pixel occupies.
- Largest size at your reference is pixel width and height divided by the reference PPI.
Calculations keep full precision; only the displayed figures are rounded to two decimals, and the comparison with your reference uses the unrounded value. The diagram illustrates centered placement only.
Questions, answered
What is PPI, and is it the same as DPI?
PPI (pixels per inch) is how many pixels of your image land in each printed inch. DPI (dots per inch) describes the dots a printer lays down and is a property of the printer, not your file. This calculator reports PPI.
Is 300 PPI required for printing?
No. 300 PPI is a common reference for prints viewed up close, which is why the Handheld viewing distance uses it, but it is a reference target, not a rule. Large-format pieces viewed from a distance can look fine well below it, and the right number depends on the product, the source image and the viewing distance.
What is the difference between fit and fill?
Fit scales the image so the whole picture is visible inside the print, which can leave empty margins when the shapes differ. Fill scales the image so it covers the whole print, which trims the edges that fall outside the print area. Both keep the image proportional; neither stretches it.
Can I raise the resolution by changing the file's PPI setting?
Changing the resolution tag alone does not add detail; it only changes how the same pixels are labeled. Resampling can add pixels, but it cannot certify that missing detail has been recovered.
Does the calculator include bleed?
No. It is a plain numerical estimate with no bleed or trim allowance. If your piece prints edge to edge, use the selected product's template and full-bleed specification in the Designer rather than assuming a fixed bleed.
Is my photo uploaded?
No. Your image is read by your browser and never uploaded. The checker decodes the file locally to read its pixel size and draw the preview and loupe; nothing is sent to InkFE, stored, or tracked, and the shareable link contains numbers only, never the image.
What does viewing distance change?
Only the reference target the quality bands are measured against: about 300 PPI for prints held in the hand, 200 for a desk or wall at arm's length, 150 across a room and 100 for banners and large format. Excellent means the effective PPI meets the target, Good is at least three quarters of it, Fair at least half, Poor below that. These are reference targets for typical viewing, not manufacturer requirements, and the effective PPI itself does not change.
Does a good PPI number guarantee a sharp print?
No. PPI only describes how densely the pixels are placed. Sharpness also depends on the original capture, compression, paper, process and viewing distance. Treat the number as a sizing estimate and use the product's template and proof for production decisions.
