Inches to Pixels Converter: Convert Inches to PX at Any DPI
To convert inches to pixels, multiply inches by DPI. At 96 DPI, 1 inch equals 96 pixels. At 300 DPI, 1 inch equals 300 pixels. The formula is: pixels = inches x DPI.

How Inch to Pixel Conversion Works
Converting inches to pixels is essential when translating physical design specifications into digital formats. This inch to pixel conversion determines the pixel requirements for any canvas before you build, print, or export it. The formula is simple:
Pixels = Inches x DPI
The DPI setting determines the resolution. Web designs typically use 96 DPI, while print projects require 300 DPI for sharp, professional output.
Common Use Cases
- Creating print-ready files: Set up a document at the correct pixel dimensions for print at 300 DPI.
- Banner and signage: Calculate pixel requirements for large-format printing.
- Photo cropping: Determine the pixel dimensions needed for a specific print size.
- UI design specs: Convert physical size requirements into pixel values for screen layouts.
Standard Document Sizes in Pixels
- Letter (8.5 x 11 in) — 816 x 1056 px at 96 DPI, 2550 x 3300 px at 300 DPI
- A4 (8.27 x 11.69 in) — 794 x 1123 px at 96 DPI, 2481 x 3507 px at 300 DPI
- 4 x 6 in photo — 384 x 576 px at 96 DPI, 1200 x 1800 px at 300 DPI
- 5 x 7 in photo — 480 x 672 px at 96 DPI, 1500 x 2100 px at 300 DPI
Why Does DPI Matter for Inch-to-Pixel Conversion?
DPI directly determines how many pixels fit inside each physical inch. A higher DPI packs more pixels per inch, producing sharper detail at the same physical size. When you convert 8 inches at 96 DPI, the result is 768 pixels. The same 8 inches at 300 DPI yields 2,400 pixels. That difference of 1,632 pixels translates to roughly 4x more image data, which is why print-ready raster image dimensions are significantly larger than web graphics at the same visual size. Choosing the wrong DPI produces images with either insufficient resolution for print or unnecessarily large file sizes for web.
How Do You Set Up a Print-Ready Document?
Start by determining the final print size in inches. Multiply width and height by 300 to get the canvas pixel dimensions for professional quality. A 5x7 inch photo print needs a 1,500 x 2,100 pixel canvas, which represents the minimum pixel dimensions for sharp output at that size. For large posters viewed from several feet away, 150 DPI is acceptable, so a 24x36 inch poster only needs 3,600 x 5,400 pixels instead of 7,200 x 10,800. Always add 0.125 inches (bleed) to each edge when preparing files for commercial printing, as the trimming process can cut into the design area.
Common Inch Measurements Converted to Pixels
- 1 inch — 96 px at 96 DPI, 300 px at 300 DPI
- 2 inches — 192 px at 96 DPI, 600 px at 300 DPI
- 4 inches — 384 px at 96 DPI, 1,200 px at 300 DPI
- 6 inches — 576 px at 96 DPI, 1,800 px at 300 DPI
- 8 inches — 768 px at 96 DPI, 2,400 px at 300 DPI
- 12 inches — 1,152 px at 96 DPI, 3,600 px at 300 DPI
Practical Quality Notes for Inches to Pixels Converter
This calculator is most helpful when the result is tied to a real workflow, not treated as a loose number. For Inches to Pixels Converter, verify the physical measurement, the target DPI, and whether the output is for screen preview, print, signage, or layout planning. That context prevents the common mistake of copying a pixel value into a print, web, or CSS workflow where the reference size is different.
Inches to Pixels Converter uses pixels = inches x DPI; a 10 inch width is 960 px at 96 DPI and 3000 px at 300 DPI. If the number looks unexpectedly large or small, check the unit direction first, then check the DPI, base font size, viewport width, or physical measurement that controls the calculation.
A good review pass for Inches to Pixels Converter is simple: calculate once, compare against a known example, and preview the final output at the size people will actually see. To convert inches to pixels, multiply inches by DPI. At 96 DPI, 1 inch equals 96 pixels. At 300 DPI, 1 inch equals 300 pixels. The formula is: pixels = inches x DPI.
Checks Before You Use the Result
- Confirm that Inches to Pixels Converter is using the same input unit your source file or design brief uses.
- Save the DPI, viewport, or font-size setting next to the final Inches to Pixels Converter value so another person can reproduce it.
- Preview the Inches to Pixels Converter output on the target medium before sending it to print, publishing it, or adding it to CSS.
- Recalculate Inches to Pixels Converter after resizing, cropping, changing aspect ratio, or changing the root font-size or viewport assumption.
When the Number Needs a Second Look
Recheck the result if the project moves from screen to print, from desktop to mobile, from one social platform placement to another, or from a draft export to a production file. Small context changes can make a correct Inches to Pixels Converter answer wrong for the final job.

Frequently Asked Questions
Multiply the number of inches by the DPI (dots per inch). For example, 10 inches at 96 DPI equals 960 pixels (10 x 96 = 960). The DPI setting determines how many pixels represent one physical inch.
At 96 DPI, 1 inch equals exactly 96 pixels. This is the standard DPI for web design on Windows displays and is the most commonly used value for screen-based design work.
At 300 DPI, 1 inch equals 300 pixels. This is the standard resolution for professional print output, including magazines, brochures, and high-quality photo prints.
8.5 inches at 300 DPI equals 2550 pixels (8.5 x 300 = 2550). This is the pixel width of a standard US Letter page when set up for professional print output.
An A4 page at 300 DPI is 2480 x 3508 pixels (8.27 in x 300 = 2481 width, 11.69 in x 300 = 3507 height, commonly cited as 2480 x 3508). Use these dimensions when setting up A4 print documents in Photoshop, Illustrator, or InDesign.
4 inches at 300 DPI equals 1200 pixels (4 x 300 = 1200). At 96 DPI the same 4 inches equals 384 pixels. Use 300 DPI for print and 96 DPI for standard web and screen work.
Use 300 DPI for standard print output such as brochures, photos, and business cards. Use 150 DPI for large-format items like posters and banners viewed from a distance. Screen and web work uses 96 DPI on most displays.
In Photoshop, go to Image > Canvas Size or File > New and enter your dimensions in inches with the resolution set to 300 PPI for print. Photoshop multiplies the inch value by the PPI setting to calculate the pixel dimensions automatically.
When converting from inches to pixels, yes: a higher DPI produces more pixels for the same physical size. When an image already exists, changing DPI in metadata only changes its print size, not the actual pixel count.
