Pixels to Inches Converter

Convert pixels to inches or inches to pixels. Enter a value and choose the PPI for your image.

Pixels to inches

Inches to pixels

Use your print PPI. CSS uses 96 px per inch.

Units & advanced options

Enter one dimension using a decimal point. Values from 0 to 100,000,000; up to 4 decimal places.

Result at 300 PPI

1,200 px

4 in × 300 PPI = 1,200 px

PPI matters: 1200 pixels = 4 inches at 300 PPI, or 12.5 inches at 96 PPI. For CSS layout, select the fixed 96 px/in context in the advanced options.

Convert a full image: width × height to inches

Enter both pixel dimensions to get the complete print size in inches and centimeters, with paper and photo presets. Need the DPI of an image at a size you already chose? Use the DPI calculator.

300 is an editable planning example, not a universal print-quality rule.

Use a decimal point, without commas. Physical lengths and PPI accept up to 4 decimal places.

How to convert pixels to inches

Find the pixel dimensions in your image’s properties, choose the print density, and divide each dimension by that PPI. To work in the opposite direction, multiply the size in inches by PPI.

Pixels to inches

inches = pixels ÷ PPI

2400 px ÷ 300 PPI = 8 inches

Inches to pixels

pixels = inches × PPI

8 in × 300 PPI = 2400 pixels

Example: a 2400 × 3000 pixel photo

At 300 PPI, the width is 2400 ÷ 300 = 8 inches and the height is 3000 ÷ 300 = 10 inches. The complete print measures 8 × 10 inches, or 20.32 × 25.4 cm.

At 150 PPI, that same image measures 16 × 20 inches. The pixel count stays the same; fewer pixels are placed in each inch. If you need a different shape, check the crop before calculating the final size.

Definitions: NIST’s inch definition and W3C’s CSS units. See our calculation methods and rounding rules.

Which PPI should I use?

For a print, start with the provider’s specification at the intended output size. For a web layout, use CSS units. These numbers describe different contexts:

Image density and CSS layout use different assumptions
DensityWhat it means1200 px in inches
72 PPIAn image-density setting, not a universal screen standard.16.666667 in
96 PPI / CSS96 image pixels per print inch, or the fixed CSS px/in ratio in CSS mode.12.5 in
150 PPIA lower print density; acceptability depends on the image and output.8 in
300 PPIThe starting print example in our calculators. Check your provider’s needs.4 in

A printer’s DPI specification is not the image PPI. Nor does setting metadata to 300 PPI add image detail. Read PPI vs. DPI or what changes when you edit PPI without resampling.

Frequently asked questions

How do I convert pixels to inches?

Divide the number of pixels by the image’s pixels per inch (PPI). For example, 1200 pixels ÷ 300 PPI = 4 inches. Repeat the calculation for the other dimension if you need the complete print size.

How many pixels are in one inch?

At 300 PPI, one inch of print contains 300 image pixels. At 150 PPI, it contains 150. There is no single physical size for an image pixel. CSS has its own fixed ratio of 96 CSS pixels per CSS inch.

What is 1920 × 1080 pixels in inches?

At 300 PPI, 1920 × 1080 pixels measures 6.4 × 3.6 inches. At 150 PPI it measures 12.8 × 7.2 inches, and at 96 PPI it measures 20 × 11.25 inches. These are calculated sizes, not recommendations for print quality.

Should I use 72, 96 or 300 PPI?

Use the image density required by your print provider or chosen for your project. The converter starts at 300 PPI as an example. Choose the CSS context for web layout, where 96 px per CSS inch is fixed. A screen or image tagged 72 PPI does not make every pixel physically 1/72 inch wide.

Are PPI and DPI the same thing?

PPI describes image pixels per inch. Printer DPI describes ink or toner dots per inch. They are different measurements, even when a brief loosely asks for a “300 DPI image.” Confirm that the brief means a 300 PPI image at the final print size.

How do I convert inches back to pixels?

Multiply inches by PPI. An 8-inch edge at 300 PPI needs 2400 pixels. The inverse converter above gives a measurement; the full image calculator also lets you choose nearest or upward rounding for a whole-pixel canvas.

Does changing PPI make an image sharper?

Changing only the PPI metadata changes the intended print size, not the number of pixels or the captured detail. Enlarging a file by resampling creates more pixels but does not recover detail that was absent from the original.

Can I convert pixels to centimeters or millimeters?

Yes. Open Units & advanced options in either converter. After dividing pixels by PPI, multiply inches by exactly 2.54 for centimeters or 25.4 for millimeters. The conversion still depends on the chosen PPI.
