Convert pixels to centimeters at any DPI

Everything depends on the resolution you choose. At the standard screen value of 96 DPI one pixel equals about 0.0265 cm, while at the 300 DPI used for print only 0.0085 cm. To convert any pixel count into centimeters, multiply it by 2.54 and divide by the DPI value.

The formula is simple and comes from a fixed relationship: one inch equals exactly 2.54 cm. The full formula is number of centimeters = number of pixels × 2.54 ÷ DPI. With two known values – pixel count and target resolution – you can instantly calculate the third.

The easiest way is to type the pixel count into the converter and pick the DPI you need – the result appears straight away. If you would rather calculate by hand, use the formula number of centimeters = number of pixels × 2.54 ÷ DPI. For 500 px at 300 DPI you get 500 × 2.54 ÷ 300, which equals roughly 4.23 cm.

One hundred pixels on a 96 DPI screen equals exactly 2.65 cm – roughly the width of an adult thumb. In 300 DPI print the same 100 pixels covers only 0.85 cm, and at 600 DPI just 0.42 cm. This is a handy value to remember because it shows up frequently in button and icon sizes on websites.

Two hundred pixels on a 96 DPI screen equals about 5.29 cm. In 300 DPI print the same 200 pixels covers only 1.69 cm, because more dots fit on one inch. At 600 DPI used for high-end photo print it is only 0.85 cm.

Three hundred pixels equals about 7.94 cm on a 96 DPI screen and exactly 2.54 cm in 300 DPI print – exactly one inch. The relationship is no coincidence: the 300 DPI standard literally means that 300 dots fit on each inch of print. The value of 300 px often matches a product thumbnail size in an online store.

One thousand pixels at 96 DPI equals about 26.46 cm – roughly the width of an A4 sheet with margins. In 300 DPI print the same 1,000 pixels covers 8.47 cm – enough for a business card or a small photo. At 150 DPI used for posters and brochures you get 16.93 cm, a format close to a postcard.

Five hundred pixels match about 13.23 cm on a 96 DPI screen and 4.23 cm in 300 DPI print. The value of 500 px is a popular width for ad banners and avatars, so it is worth remembering for quick size estimates.

One thousand and eighty pixels is exactly 28.58 cm on a typical 96 DPI screen – the height of a Full HD image displayed at 1:1 scale. In 300 DPI print the same 1,080 pixels covers only 9.14 cm, roughly the width of a business card. At 150 DPI used for posters you get 18.29 cm.

One thousand nine hundred and twenty pixels is exactly 50.80 cm on a 96 DPI screen – the width of a Full HD image. In 300 DPI print the same value covers only 16.26 cm, and at 600 DPI just 8.13 cm. This number is worth remembering because it shows up in almost every monitor screenshot.

A full Full HD frame at 1:1 scale covers 50.80 × 28.58 cm at the 96 DPI screen standard. If you wanted to print the same image at photo-quality 300 DPI it would fit exactly on 16.26 × 9.14 cm – roughly the size of a postcard. For 4K UHD 3,840 × 2,160 px every dimension doubles: 101.60 × 57.15 cm on screen and 32.51 × 18.29 cm in print.

The 4K UHD resolution (3,840 × 2,160 px) at 1:1 scale corresponds to 101.60 × 57.15 cm at the 96 DPI screen standard – more than a meter wide, roughly the size of a 45-inch TV viewed up close. In 300 DPI print the same file fits on 32.51 × 18.29 cm, a format close to a landscape A4 sheet. At 150 DPI it is enough for a 65.02 × 36.58 cm poster.

A 2,480 px wide file at 300 DPI equals exactly 21.00 cm, the short side of an A4 sheet. A print shop will accept such a file without issues if the height is 3,508 px (29.7 cm). The same file on a 96 DPI screen would cover 65.62 cm, stretching far beyond the visible area of a regular monitor.

Six thousand pixels is a typical width for a photo from a DSLR or mid-range mirrorless camera. At 300 DPI used for photo print this gives 50.80 cm – enough for an A2 poster or a wide gallery print. If the photo has a 3:2 ratio, the other side is 4,000 px, which equals 33.87 cm.

A pixel has a physical size that follows from panel density, meaning the number of dots per inch. A 24-inch Full HD monitor holds about 92 pixels per inch, a 13.6-inch MacBook Air holds 224, and an iPhone 17 Pro holds 460. A 1,000 px graphic therefore covers 27.61 cm, 11.34 cm, and 5.52 cm respectively. Browsers even out the difference by assuming a reference pixel with a density of 96 dots per inch, which is why a page layout looks similar on every device.

Retina displays pack pixels more than twice as densely as a regular monitor – the 13.6-inch MacBook Air is rated at 224 pixels per inch. The operating system still interprets dimensions as if the panel was 96 DPI, so one physical pixel covers about 0.0113 cm there. On a 96 DPI monitor that same pixel measures 0.0265 cm. In the design panels of Photoshop, Figma, and Canva the values stay identical, and you prepare graphics at twice the resolution and export them with the @2x suffix.

In Photoshop open Image › Image Size, change the unit from pixels to centimeters and type the target DPI – the program shows the current physical size. In Canva the project dimensions panel is visible when you create a new file or via the Resize menu; switch the units to cm. Detailed walkthroughs for Photoshop, Illustrator, Figma, Canva, and Procreate are in the section above.

In Adobe Illustrator go to Edit › Preferences › Units and pick Centimeters – the unit changes across all panels and rulers immediately. Figma works differently because it operates only in pixels at a fixed 96 DPI – there is no option to switch units inside the tool. To check the physical size of a Figma project, copy the pixel value from the Design panel and paste it into our converter while setting the target DPI (96 for screen, 300 for print).

DPI (dots per inch) is the number of ink dots per inch of material and describes a printer. PPI (pixels per inch) is the number of pixels per inch of a screen and describes a monitor or display. In everyday work designers use both abbreviations interchangeably, but technically DPI is for print and PPI is for screens.
