Inches to Pixels Converter

How do you convert inches to pixels?

To convert inches to pixels, multiply the inches by your resolution in DPI: pixels = inches x DPI. At 300 DPI a 4-inch image is 1,200 pixels wide, and at 96 DPI it's 384 pixels. The math never changes; only the DPI you choose moves the result.

That single multiplication is the whole rule, but the DPI you feed it carries all the weight. DPI (dots per inch, often written PPI for screens) tells the converter how many pixels pack into every inch. A 5-inch graphic is 480 pixels at 96 DPI and 1,500 pixels at 300 DPI, and that's the same physical 5 inches both times. So before you trust any pixel number, you've got to know the resolution behind it. Pick the wrong DPI and a print job comes out blurry, or a web banner balloons to four times the file size it needed. The inches to pixels calculator above keeps that DPI choice front and center so you don't lose track of it.

If you need the reverse direction, our pixels to inches tool divides instead of multiplies: inches = pixels / DPI. The two pages are mirror images of the same formula, and they share the exact DPI logic.

Inches to pixels conversion chart (96 and 300 DPI)

This chart pre-computes the most-requested inch values across five common resolutions. Screen work usually lives at 72 or 96 DPI, print sits at 300 DPI, and large-format banners often run at 150 DPI or lower. Scan the row you need and copy the pixel count straight out.

Notice how the same inch value triples in pixel count between 96 and 300 DPI. That's not a rounding quirk; it's the formula working as designed. A 1-inch element is 72 pixels at 72 DPI, 96 pixels at 96 DPI, 150 pixels at 150 DPI, 300 pixels at 300 DPI and 600 pixels at 600 DPI. The pixel total climbs in lockstep with the resolution, which is exactly why two converters can hand you different answers for the same inch input. Once you spot that pattern, you'll never be surprised by a result again.

How many pixels is 1, 2, 4 or 8 inches?

Here are the value answers people search for most, worked out at the two resolutions that matter day to day. At 96 DPI you're sizing for screens; at 300 DPI you're sizing for print. The table below gives you both without any mental math.

Reading it back in plain words: 1 inch is 96 pixels on screen and 300 pixels in print, 2 inches doubles to 192 and 600 pixels, 4 inches reaches 384 and 1,200 pixels, and 8 inches lands at 768 and 2,400 pixels. The 8.5 and 11 rows cover US Letter dimensions, which we'll expand on further down.

So how many pixels is in one inch? It's whatever DPI you set, full stop. One inch always equals exactly the DPI value in pixels, because the formula is inches x DPI and you're multiplying by 1. That's the shortcut worth memorizing: the number of pixels in a single inch is the same as the resolution you picked. Set 96 and you get 96; set 300 and you get 300. There's no fixed pixel count for an inch on its own, which trips up a lot of people who expect one universal answer. The deeper dive on this lives in the DPI guide, but for converting inches you've now got the whole story.

How to use the inches to pixels converter

The tool takes three quick steps, and you'll have your answer in seconds. There's no sign-up and no limit on conversions.

1. Enter the length in inches. Decimals are fine, so 5.5 inches works just as well as a whole number.
2. Choose 96 DPI for screen or 300 DPI for print, or type a custom value if your printer or design spec calls for something else.
3. Read the pixel result and copy it into your design app, CSS, or print order.

If you're working in a different starting unit, we've got matching tools for cm to pixels and feet to pixels on the home page, all using the same DPI engine.

What DPI should you use for web, print or large-format?

The right DPI depends entirely on how far the viewer's eyes sit from the finished piece. Closer viewing needs more pixels per inch; greater distance lets you use fewer. Here's the quick rule of thumb for each use case, with deeper detail in the DPI guide.

• Web and screen (72-96 DPI): Use 96 DPI for standard web graphics and 72 DPI for legacy screen work. Anything higher just inflates the pixel dimensions without making the image look sharper on a monitor.
• Retina and high-density displays (192 DPI): Double the screen value to 2x so images stay crisp on phones, tablets and modern laptops. A 96 DPI graphic exported at 192 DPI covers most retina cases.
• Standard print (300 DPI): This is the gold standard for photos, brochures and anything held in the hand. At 300 DPI text edges and fine detail stay clean under close inspection.
• Large-format and banners (100-150 DPI): Posters, signage and trade-show banners get viewed from several feet away, so 150 DPI (or even 100) prints sharp while keeping file sizes manageable.

When you're unsure, ask your print vendor which DPI their press expects, then plug that number into the converter. It'll handle the rest.

One honest caveat worth stating plainly: bumping the DPI on an image that was captured at low resolution won't add detail that wasn't there. If your source file is 500 x 500 pixels, exporting it at 300 DPI just spreads the same pixels across fewer inches; it can't invent new ones. So treat DPI as a target for how big your canvas needs to be, not as a magic sharpness dial. Start with enough pixels for the size you want, and the conversion math will line up with a crisp final print every time.

Common paper and photo sizes in pixels

Standard documents and photo prints have fixed inch dimensions, so their pixel sizes are easy to pre-calculate. US Letter (8.5 x 11 in) is 2,550 x 3,300 pixels at 300 DPI, or 816 x 1,056 pixels at 96 DPI. A 4 x 6 photo is 1,200 x 1,800 pixels at 300 DPI, and a 5 x 7 print is 1,500 x 2,100 pixels at the same resolution.

A4 (8.27 x 11.69 in) comes out to roughly 2,480 x 3,508 pixels at 300 DPI, which is why design templates for A4 and Letter aren't interchangeable. If you're prepping a full sheet, set the converter to your print DPI and run each dimension separately. For the complete reference, see paper sizes in pixels and photo print sizes in pixels, where we've laid out every common format.

A quick word on bleed: print shops usually want an extra 0.125 inch on each edge so trimming doesn't leave a white sliver. That turns an 8.5 x 11 Letter into an 8.75 x 11.25 canvas, or 2,625 x 3,375 pixels at 300 DPI. It's a small add, but skipping it is the single most common reason a print order bounces back. Run your with-bleed dimensions through the converter the same way, and you'll hand the printer a file that fits their template on the first try.

Frequently asked questions

How do you convert inches to pixels?

Multiply inches by your resolution: pixels = inches x DPI. At 300 DPI a 4-inch image is 1,200 pixels. At 96 DPI it's 384 pixels.

How many pixels is 1 inch?

At 96 DPI, 1 inch is 96 pixels. At 300 DPI it's 300 pixels. One inch equals exactly the DPI value in pixels, so the number you pick is the answer.

How many pixels is 8.5 x 11 inches?

A US Letter page is 2,550 x 3,300 pixels at 300 DPI, or 816 x 1,056 pixels at 96 DPI. See our paper sizes in pixels for the full list.

Is 300 DPI enough for printing?

Yes. 300 DPI is the standard for sharp printed photos and documents you'll view up close. Large-format prints viewed from a distance can drop to 100-150 DPI and still look crisp.

What DPI should I use for web images?

Use 96 DPI for screen and web graphics. Higher DPI won't improve on-screen sharpness; it only inflates the pixel dimensions and the file size. The DPI guide covers retina exceptions.

Why do inches to pixels results differ between tools?

They're using different DPI defaults. One tool assumes 72, another 96, another 300. Inches don't change, but the pixel count does, so always confirm which DPI a converter is set to.
