Preview How Your Photo Will Crop

Compare an image ratio with common photo and paper formats, estimate crop loss and choose the orientation that preserves more of the image.

Quick answer

A full-bleed print crops whenever the image and paper have different aspect ratios. Upload a local image or enter its pixels, choose a print preset and compare fill versus fit before ordering.

retained area = smaller aspect ratio ÷ larger aspect ratio

When to use this tool

Use it for a specific print decision.

  • Use it before ordering a borderless photo when the camera ratio and frame ratio may differ.
  • Use it to compare fill, which removes image content, with fit, which preserves the image and can leave borders.
  • Use the position controls to protect faces, text, horizons or other subject-critical areas before calculating post-crop PPI.
How to use it

A result you can reproduce.

  1. Enter the image dimensions to establish its aspect ratio.
  2. Choose the intended paper or photo size.
  3. Compare the retained and cropped percentages before editing the composition.

Every result is calculated in the page from the displayed inputs. Your printer's written production specification remains the final authority.

Worked example · quick scenario

See the basic numbers in context.

A portrait 2:3 camera image retains about 83.3% of its area when it fills an 8 × 10 (4:5) print, so about 16.7% is cropped from the long direction.

Worked calculation

Follow the arithmetic from input to decision.

Inputs

  • Source ratio: 3:2
  • Target print: 8 × 10 in (4:5)
  • Mode: fill

Calculation

  1. Source ratio = 1.5 and target ratio = 1.25.
  2. Retained fraction = 1.25 ÷ 1.5 = 0.8333.
  3. Cropped fraction = 1 − 0.8333 = 0.1667, or about 16.7%.

A 3:2 image loses about 16.7% of its area when it fills an 8 × 10 print.

Assumptions

What must be true for this calculation to apply.

  • The calculation models a centred geometric fill crop and compares aspect ratios only.
  • Orientation is aligned before the ratios are compared.
  • The retained-area estimate assumes rectangular source and target frames.

From calculation to production

Verify the Aspect ratio & crop result with your real file.

A full-bleed print crops whenever the image and paper have different aspect ratios. Upload a local image or enter its pixels, choose a print preset and compare fill versus fit before ordering. Then compare the result with the print provider's written specification.
