Is Your Image Ready to Print?

Upload an image and check effective PPI, maximum print sizes, crop loss, bleed canvas and safe area without sending the file anywhere.

Quick answer

A print-ready image has enough real pixels for the final physical size, after any crop. This checker reads those pixels locally, calculates effective PPI and shows realistic maximum sizes at 150, 240 and 300 PPI.

effective PPI = remaining pixels ÷ final printed inches

When to use this tool

Use it for a specific print decision.

  • Use it after choosing the exact image file and before ordering a standard photo, paper or wall-print size.
  • Use it when a printer warns that a file is low resolution and you need to see whether crop, orientation or target PPI is causing the shortfall.
  • Use it to compare maximum physical sizes at 150, 240 and 300 PPI without changing or uploading the source image.
How to use it

A result you can reproduce.

  1. Choose the final image file or enter its pixel dimensions.
  2. Select the physical print size and orientation.
  3. Compare effective PPI, crop and bleed results with your printer's specification.

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 3600 × 2400 px image can print 12 × 8 inches at 300 PPI, 15 × 10 inches at 240 PPI or 24 × 16 inches at 150 PPI before cropping.

Worked calculation

Follow the arithmetic from input to decision.

Inputs

  • Image: 4200 × 2800 px
  • Target print: 14 × 10 in
  • Planning targets: 300 PPI and 240 PPI

Calculation

  1. The source ratio is 4200:2800 = 3:2, while 14:10 = 7:5. A fill crop is therefore required before effective PPI is judged.
  2. Keeping the full 2800 px height, a 7:5 crop needs 2800 × 1.4 = 3920 px of width. The post-crop image is 3920 × 2800 px.
  3. The crop removes 4200 − 3920 = 280 px from the long direction, which is 280 ÷ 4200 = 6.67% of the source width (and source area).
  4. Effective density after the crop is 3920 ÷ 14 = 280 PPI horizontally and 2800 ÷ 10 = 280 PPI vertically.
  5. A true 300 PPI 14 × 10 in raster would require 4200 × 3000 px. A 240 PPI raster requires 3360 × 2400 px.

Without upscaling, this exact 14 × 10 in fill crop prints at 280 PPI. It does not meet a 300 PPI requirement, but it exceeds a 240 PPI requirement.

Assumptions

What must be true for this calculation to apply.

  • The entered 4200 × 2800 px dimensions are the final source dimensions before the print-ratio crop.
  • The image fills the 14 × 10 in print with no borders, and the crop is centered only for the arithmetic example; crop placement can shift in production.
  • No resampling or AI upscaling is applied before the effective-PPI calculation.
  • 300 PPI and 240 PPI are planning requirements supplied by a workflow or print provider, not universal quality grades.

Verify the Print readiness checker result with your real file.

A print-ready image has enough real pixels for the final physical size, after any crop. This checker reads those pixels locally, calculates effective PPI and shows realistic maximum sizes at 150, 240 and 300 PPI. Then compare the result with the print provider's written specification.
