Clarity and resolution

Check a photo's resolution before printing

Ask the printer for the required pixel dimensions at your chosen size. A screen preview cannot show how a large print will look, especially when fine texture has been generated.

You choose your own source and review the current cost before generation.

A situation you may recognize

A 2400 × 3000 image is intended for an 8 × 10 inch print.

The arithmetic gives 300 pixels per inch before any crop. A tighter crop reduces that margin. Confirm the printer’s requested dimensions and inspect a small proof; a pixel calculation alone does not establish image quality or paper behavior.

01

Locate the problem before editing

Order a small proof or inspect a crop at intended print scale. Keep original and enhanced versions so you can choose the more natural result.

IN PRACTICE

Work through a practical example

01

Choose the next move

Use the printer’s requirements, viewing distance and subject detail together. A numeric calculation is preparation, not a guarantee of an acceptable print.

02

Make the first version

Divide pixels by pixels per inch to estimate print inches before cropping. A 1200-pixel side at 300 ppi is 4 inches, about 10.2 cm. Recalculate after the final crop, then order or print a small proof to inspect the actual subject detail.

03

Have these ready

Ask the printer for the intended physical size and preferred pixels per inch. Keep the actual pixel dimensions of your file.

Check your own pixel dimensions

Read width and height from the original file. Set the print density your printer requests; 300 ppi here is an example, not a universal requirement.

This is dimension arithmetic, not a promise of recovered detail or accepted tool input. Check the real returned file and a print proof.
02

Look closely at the examples

Try this before committing

At a requested 300 pixels per inch, a 6 × 4 inch print needs 1800 × 1200 pixels. This is a calculation example, not a universal print requirement. Ask the printer for its target and order a proof when texture matters.

Questions for this project

Will changing a 72 dpi tag to 300 fix the image?

Changing metadata alone does not add pixels or trustworthy detail. Distinguish a density tag from resampling. Check pixel dimensions, crop and print size; if the source lacks detail, seek a better original or use a smaller print.
