Inches to Pixels Converter | Free DPI & PPI Calculator

Converting inches to pixels is an everyday task for designers, developers and photographers, but the answer is never a single fixed number. An inch is a physical measurement, while a pixel is a digital unit whose size depends on resolution, measured in DPI (dots per inch) or PPI (pixels per inch). The same one inch can equal 72 pixels, 96 pixels or 300 pixels depending on whether the file is made for a screen or a printer. Understanding how inches, pixels and DPI relate helps you set the right canvas size for web, print and photo editing before you start designing.

How Many Pixels Are in an Inch?

The quick answer: 1 inch = 96 pixels at 96 PPI, and 1 inch = 300 pixels at 300 DPI. The inch never changes. The pixel count does, because it depends on the resolution you are working at.

That is why every designer, photographer and developer eventually asks the same question: how do I convert inches to pixels without guessing? The Wally Inches to Pixels Converter answers it in one step. Enter your inches, pick a resolution, and the pixel value appears live.

The Inches to Pixels Formula

The formula is short:

Pixels = Inches × PPI

A 3-inch width at 96 PPI is 3 × 96 = 288 px. The same 3 inches at 300 DPI is 3 × 300 = 900 px. Same physical size, more than three times the pixels.

Going the other way is just as simple:

Inches = Pixels ÷ PPI

A 1920 px wide image is 20 inches wide at 96 PPI, but only 6.4 inches wide at 300 DPI. This is the reason a photo that looks sharp on screen can print small or soft.

PPI vs DPI: What Is the Difference?

PPI (pixels per inch) describes how many pixels fit into an inch of a digital image or screen. DPI (dots per inch) describes how many dots of ink a printer places in an inch. Strictly speaking they measure different things. For converting inches to pixels, though, they work the same way in the formula. If a print shop asks for 300 DPI and your design tool asks for 300 PPI, use 300 in both.

Which DPI or PPI Should You Use?

Pick the resolution based on where the file will end up:

  • 72 PPI: the older screen standard. You will still see it in legacy documentation and some web workflows.
  • 96 PPI: the web standard. CSS defines 1 inch as 96 pixels, so start here for websites, apps and anything viewed on a screen.
  • 150 PPI: mid-range print. Good for large-format work viewed from a distance, such as banners and posters.
  • 300 DPI: the professional print standard. Business cards, brochures, flyers, magazines and photo prints all start here.
  • 600 DPI: high-resolution output for fine art prints, detailed line work or anything examined up close.

Need another value? The converter also accepts a custom PPI, so you are not limited to the presets.

Common Print Sizes in Pixels at 300 DPI

These are the canvas sizes designers set up most often for print:

Print sizeInchesPixels at 300 DPI
Business card3.5 × 21050 × 600 px
Photo print4 × 61200 × 1800 px
Photo print5 × 71500 × 2100 px
Photo print8 × 102400 × 3000 px
US Letter8.5 × 112550 × 3300 px
A48.27 × 11.692480 × 3508 px
Tabloid11 × 173300 × 5100 px

If your photo is smaller than the number shown for your print size, expect softer edges and less detail on paper. Check the pixel count before you send a file to the printer, not after.

The Same Sizes on Screen at 96 PPI

For web layouts and on-screen documents, the numbers are much smaller:

  • US Letter (8.5 × 11 in): 816 × 1056 px
  • A4 (8.27 × 11.69 in): 794 × 1123 px
  • 1 inch: 96 px

These are CSS pixels. Modern phones and Retina-style displays pack more physical pixels into the same CSS pixel, commonly two or three. A 100 px wide element still counts as 100 CSS pixels in your layout, but it is drawn with 200 or 300 device pixels. That is why designers export web images at 2x for sharp results on high-density screens, and why the custom PPI field is handy when a spec sheet gives an unusual density.

Where You Will Use Inches to Pixels Conversion

Web design and development. Translate physical specs into pixel values for layouts, images and CSS at the 96 PPI standard. If you also care about how fast those images load, our Google PageSpeed optimization service covers image weight and Core Web Vitals, and our WordPress web design team builds sites with the right image sizes from day one.

Print design. Business cards, brochures, flyers and posters need exact canvas sizes at 300 DPI before you start. If you would rather hand the work off, see our logo design, flyer design and brochure design services.

Photo editing. Work backwards from the print size to find the minimum pixel dimensions your photo needs, then confirm in Photoshop or Lightroom.

Social media graphics. Cover images, banners and thumbnails come as pixel specs, but you may also need the printed equivalent for event material. Our social media designing service covers both.

Documents and certificates. PDF, resume and certificate edits often involve fixed page sizes. If a file needs reworking, our PDF editing and resume editing services can handle it.

Frequently Asked Questions

How do I convert inches to pixels?
Multiply the inch value by the PPI of your project: Pixels = Inches × PPI. A 4-inch canvas is 384 px at 96 PPI and 1,200 px at 300 DPI. Most mistakes come from using the wrong PPI, not from the math.

How many pixels are in an inch?
It depends on the resolution. At 96 PPI, 1 inch is 96 pixels. At 300 DPI, 1 inch is 300 pixels. At 72 PPI, it is 72 pixels.

What DPI should I use for print?
300 DPI is the standard for commercial print such as business cards, brochures and magazines. For large banners and posters viewed from a distance, 150 DPI is usually enough. Use 600 DPI for fine art or technical work examined closely.

What PPI should I use for a website?
96 PPI. It matches the CSS definition of an inch and the default for most browsers and operating systems. 72 PPI appears in older guidance but is rarely needed today.

Is PPI the same as DPI?
Not technically. PPI refers to pixels on a screen or image, DPI to printed dots. For inch-to-pixel conversion they use the same formula, so use the same number in either field.

How do I convert pixels to inches?
Divide the pixel value by the PPI. A 1,500 px wide image at 300 DPI prints 5 inches wide. In the converter, press the swap button and the tool does it for you.

How many pixels do I need for a good photo print?
Work backwards from 300 DPI: a 4 × 6 print needs at least 1,200 × 1,800 px, and a 5 × 7 needs 1,500 × 2,100 px. Smaller files print softer.

How many pixels is an A4 page?
At 300 DPI, A4 is about 2480 × 3508 px. At 96 PPI it is about 794 × 1123 px.

Can I use a custom PPI for high-density screens?
Yes. Type any value in the custom PPI field and the result recalculates instantly.

Is the Inches to Pixels Converter free?
Yes. It is free, needs no account and nothing to install.
