Print Size & DPI Calculator

Enter your image's pixels to see the largest sharp print size, its dimensions in inches and cm, and whether it's 300 DPI print-ready.

300 DPI = sharp gallery print · 150–299 DPI = fine at arm's length or larger frames · under 150 DPI = visibly soft. Best-fit orientation assumed.

Why print resolution matters

On Etsy, a blurry print means a refund and a bad review. A few seconds here saves both.

Print without refunds

Low-resolution files print blurry and earn one-star reviews. Check every size is sharp before you list it.

Pixels → inches & cm

Instantly convert your image's pixel dimensions into real-world print sizes at any DPI, in both inches and centimeters.

Find your largest size

See the biggest frame size your image can fill at a crisp 300 DPI — so you list the sizes that actually look good.

How to work out your print size from pixels

What determines the size you can sell, how to read your own files honestly, and where aspect ratio quietly breaks a listing.

How print size is calculated

Your print size is your pixel count divided by the resolution you print at. A 4800 × 6000 pixel image at 300 DPI prints 16 × 20 inches, because 4800 ÷ 300 = 16 and 6000 ÷ 300 = 20. Nothing else about the file matters — not the file size in megabytes, not the format, not what Photoshop says the document dimensions are.

That last point trips people up. An image editor lets you set a document to 8 × 10 inches at 300 DPI while the underlying image only has 800 × 1000 pixels. The document claims to be print-ready; the pixels say otherwise, and the printer follows the pixels. Always size from the pixel dimensions.

Changing DPI does not change your image

Re-tagging a file from 72 to 300 DPI in an editor adds no detail — it only relabels how densely the existing pixels should print, which makes the print smaller, not sharper. The only way to print bigger and stay sharp is more pixels.

The largest size you can sell

Take your shortest pixel edge, divide by 300, and that is the biggest sharp dimension you have. Everything larger is a compromise you are asking the buyer to absorb.

4800 × 600016 × 20"Up to 16×20"
7200 × 1080024 × 36"Every standard frame size

This is why most raw AI generations are not sellable as-is. A default 1024 × 1024 output is a 3.4-inch print. It has to be upscaled before it can carry a wall-art listing, and upscaling well means adding detail rather than stretching what is there.

Choosing a resolution honestly

The same thresholds the calculator uses for its verdicts.

Viewing distance is the honest variable. Nobody inspects a 24 × 36 inch poster from six inches away, so 200 DPI at that size can look fine on a wall. An 8 × 10 inch print sits at arm's length on a desk, and there 300 DPI is the floor, not the target.

Aspect ratio is the other half of the problem

Having enough pixels does not mean your art fits the frame. A square generation cannot fill an 11 × 14 inch frame without either cropping the edges or leaving borders, and buyers who print it will notice.

  • The US frame sizes divide into two families: 4:5 (4×6", 8×10", 16×20") and roughly 4:5.1 (11×14"), which are close but not identical.
  • The A-series (A4, A3, A2) is a single 1:√2 ratio all the way up, which is why one A-sized file scales cleanly across the whole range.
  • Selling both families from one design means exporting at least two crops, not one file relabelled twice.

Before you commit a design to a size bundle, work out which frames your ratio actually fits.

A pre-listing checklist

  1. 1Read the real pixel dimensions off the file, not the document setup in your editor.
  2. 2Divide the short edge by 300 to get your maximum sharp size.
  3. 3Check your aspect ratio against the frame families you plan to sell.
  4. 4Export one file per aspect ratio rather than one file for every listed size.
  5. 5State the exact pixel dimensions and DPI in the listing description — it prevents most refund requests before they happen.

To verify a finished file against every standard size at once, run the file through the resolution checker.

FAQ

Have any questions?

Everything you need to know about this free tool.

What DPI do I need for print-ready art?

300 DPI is the standard for sharp, gallery-quality prints at normal viewing distance. 150–299 DPI can be fine for larger pieces viewed from further away, and anything under 150 DPI will look visibly soft.

How do I convert pixels to inches for printing?

Divide the pixel dimension by the DPI. A 3000px-wide image at 300 DPI prints 10 inches wide (3000 ÷ 300). This tool does it for both dimensions and shows the result in inches and centimeters.

What size can I print my image at?

It depends on the pixel dimensions. The calculator shows your largest sharp size at 300 DPI, plus a readiness verdict for every common frame and A-series size, so you know exactly which listings will look crisp.

Does changing DPI change my image?

No. DPI is just how densely those pixels are printed. More pixels means you can print larger while staying sharp; fewer pixels means a smaller sharp size. The pixels themselves don't change.

Is this tool free?

Yes, completely free with no signup. Use it for every listing.
