Image DPI Checker

Image DPI Checker reads pixel width and height from your file, then calculates effective dots-per-inch when you enter the intended physical print size in inches.

It rates whether the resolution suits home inkjet, professional press, or large-format poster viewing distance—without opening Photoshop.

Print shops reject blurry posters when a 800×600 web image stretches to 24 inches wide. Checking DPI first saves reprint fees.

Designers exporting from Canva or Figma need a quick sanity check before sending wedding albums or trade-show banners to print.

• Verify wedding photo resolution before album vendor upload
• Check logo PNG pixel count for business card print specs
• Audit stock photo dimensions for billboard mockups
• Confirm passport photo pixel density at 2×2 inch output
• Compare camera export sizes before ordering canvas prints

1. 1Upload a JPG, PNG, or WebP image.
2. 2Enter the width you plan to print in inches (height can follow aspect ratio in the readout).
3. 3Read effective DPI and the quality rating the workspace displays.
4. 4If DPI is low, note target pixels and run Resize Image or AI Image Upscaler before printing.
5. 5Download or screenshot the report for print vendor tickets.

• 300 DPI is a common offset print target; large banners viewed from far away may look fine at 100–150 DPI.
• DPI is math from pixels ÷ inches—upsampling small files in an editor does not add real detail.
• Pair with Image DPI Converter when you need exact pixel dimensions for a fixed print size.
• Web images at 72 PPI reference screen density, not print—always recalculate for paper.

• The tool reports effective DPI from pixel data—embedded EXIF DPI tags may differ and are not always authoritative.
• It does not measure ink dot gain or paper absorbency—physical proofs still matter.
• Common mistake — assuming 72 DPI files print sharp at poster size: recalculate or reshoot before paying for print.
