DPI to Pixels Converter
Find the pixel dimensions of an image from its DPI and physical size. Enter the size in inches and a DPI value, and the tool returns the exact pixel count.
How do you convert DPI to pixels?
Multiply the size in inches by the DPI: pixels = inches x DPI. DPI alone isn't pixels, though. You'll also need a physical size, because DPI only tells you how many pixels sit in one inch. A 4-inch image at 300 DPI is 1,200 pixels across.
That caveat trips up a lot of people. Someone reads "300 DPI" off a printer setting and assumes it means a fixed pixel count, but it doesn't. Without a size, 300 DPI is just a density. Pair it with 2 inches and you get 600 pixels; pair it with 8 inches and you get 2,400. The size does half the work, so don't skip it.
DPI to pixels chart (72 to 600)
Here's how common inch sizes land at each DPI. We've run 1, 2, 4, 6, and 8 inches across the five standard resolutions so you can read the pixel count straight off the grid.
| Inches | 72 DPI | 96 DPI | 150 DPI | 300 DPI | 600 DPI |
|---|---|---|---|---|---|
| 1 | 72 px | 96 px | 150 px | 300 px | 600 px |
| 2 | 144 px | 192 px | 300 px | 600 px | 1,200 px |
| 4 | 288 px | 384 px | 600 px | 1,200 px | 2,400 px |
| 6 | 432 px | 576 px | 900 px | 1,800 px | 3,600 px |
| 8 | 576 px | 768 px | 1,200 px | 2,400 px | 4,800 px |
How many pixels is 300 DPI or 150 DPI?
300 DPI means 300 pixels per inch, so a 1-inch square is 300 pixels and an 8-inch photo is 2,400 pixels. 150 DPI is half that density: a 1-inch image is 150 pixels, and a 10-inch banner is 1,500 pixels. The value you pick depends on viewing distance, not just the printer.
Each resolution has a job it's built for. Here's the pixel value per inch and per ten inches for the five you'll meet most, plus where each one earns its keep.
| DPI | 1 inch | 10 inches | Where it fits |
|---|---|---|---|
| 72 | 72 px | 720 px | Legacy web baseline; soft for print |
| 96 | 96 px | 960 px | Standard screen and CSS resolution |
| 150 | 150 px | 1,500 px | Large-format work viewed from a distance |
| 300 | 300 px | 3,000 px | Print standard, viewed up close |
| 600 | 600 px | 6,000 px | Fine-art and high-detail print |
How to use the DPI to pixels calculator
It takes three quick steps. You won't need to do any math by hand once the values are in.
- Enter the physical size of your image in inches in the size field.
- Type the DPI you're targeting, for example 300 for print or 96 for screen.
- Read the pixel result the tool returns; that's the exact width or height in pixels.
To get both dimensions of a rectangle, run the calculator once for the width and once for the height. A 4 by 6 inch photo at 300 DPI gives you 1,200 by 1,800 pixels.
DPI vs PPI: what is the difference?
PPI describes pixels in a digital image or on a screen, while DPI describes the dots a printer lays down. They convert one to one when you size a file, so the number you type stays the same, but they aren't the same concept. Here's the side-by-side.
| Aspect | PPI (pixels per inch) | DPI (dots per inch) |
|---|---|---|
| What it measures | Pixels in a digital image or on screen | Ink dots a printer sprays on paper |
| Where it lives | Image files, monitors, cameras | Printers and press hardware |
| Typical value | 72, 96, or 300 for files | 1,200 to 2,400 on the device |
| For sizing math | 1 PPI maps to 1 DPI | Numerically equal for conversion |
The gap matters at the print stage. A printer can lay several ink dots down for every image pixel, so a 300 PPI file might print at 1,200 DPI on the hardware. The DPI to PPI page walks through when that distinction actually changes what you do.
What DPI should you use for your project?
Match the DPI to where the image will be seen. Going higher than you need just bloats the file without making anything look better, since the screen or paper can't show detail it can't resolve.
- Web and screen: 72 or 96 DPI is plenty; pixels are what the browser cares about.
- Standard print and photos: 300 DPI is the up-close benchmark for flyers, books, and prints.
- Large-format and banners: 150 DPI holds up because you'll view it from several feet back.
- Fine-art and gallery work: 600 DPI captures the finest detail when people lean in.
If you're unsure which value fits, the DPI guide breaks down each use case with examples and the pixel counts they need.
Frequently asked questions
How do you convert DPI to pixels?
DPI alone isn't a pixel count. You'll also need a size. Multiply the size in inches by the DPI: pixels = inches x DPI. So a 4-inch image at 300 DPI works out to 1,200 pixels across.
How many pixels is 300 DPI?
300 DPI means there are 300 pixels in every inch. A 1-inch image is 300 pixels, a 6-inch image is 1,800 pixels, and an 8-inch image is 2,400 pixels at 300 DPI.
How many pixels is 150 DPI?
150 DPI is 150 pixels per inch. A 1-inch image is 150 pixels at 150 DPI, and a 10-inch image is 1,500 pixels. It's a common choice for large prints you'll view from a distance.
How many pixels is 72 DPI?
72 DPI is 72 pixels per inch, the legacy web baseline. A 1-inch image is 72 pixels, so a 10-inch graphic is just 720 pixels. That's why 72 DPI files look soft when you print them.
What is the difference between DPI and PPI?
PPI (pixels per inch) describes digital images and screens. DPI (dots per inch) describes the ink dots a printer lays down. For conversions they map one to one, but they're measuring different things.
Does higher DPI always mean a sharper image?
Not on its own. DPI only sharpens output if the source file actually holds enough pixels. If you upscale a small photo to 300 DPI, you're inventing pixels, and it won't look crisper than the original capture.
