Inches to PX Converter Online
with Conversion Table

When you design across print and digital mediums, one of the most common challenges is translating inches—the physical world’s unit of length—into pixels, the digital world’s unit of precision.

A client may say, “The brochure header should be 8 inches wide,” or a developer might ask, “How many pixels is that?” Without a reliable conversion, you’re guessing—and that’s risky when you need pixel-perfect results.

That’s exactly why we built this Inches to PX Converter.
At our agency, we deal with both print layouts and web design mockups daily, and this converter helps our team translate real-world measurements into digital dimensions instantly and accurately. It’s simple, reliable, and built for designers, developers, and anyone working between screens and print.

What Are Inches (in) and Pixels (px)?

Inch (in)

An inch is a fixed, physical unit of measurement primarily used in the U.S. and print industry. It never changes—1 inch always equals 2.54 centimeters or 25.4 millimeters. In print and manufacturing, inches are the standard unit for paper sizes, screen dimensions, and device specifications.

Pixel (px)

A pixel, short for “picture element,” is the smallest unit of a digital image or display. Pixels don’t have a fixed physical size—they depend on screen resolution, measured as PPI (pixels per inch).
The higher the PPI, the smaller each pixel appears. For example, a 96 PPI monitor shows fewer, larger pixels per inch than a 300 PPI retina display.

So, when converting inches to pixels, you’re mapping a real-world absolute unit to a digital relative one based on a specific pixel density (PPI).

Why Convert Inches to Pixels?

Here are the real-world scenarios where our team—and thousands of creators—need this conversion:

1. Print to Web or Screen Design

When you design a 6-inch-wide logo for a flyer and want to show it accurately on a website, you need to convert that measurement to pixels.

2. Digital Mockups & Product Visualizations

If you’re displaying physical products (like T-shirts, books, or posters) in digital mockups, converting inches to pixels ensures accurate on-screen proportions.

3. UI/UX Design for Real Devices

Designers creating interfaces for touchscreens (tablets, kiosks, etc.) must understand how large an element appears physically.
For instance, a “1-inch button” must be converted into pixels depending on the device’s PPI.

4. Photo Printing and DPI Settings

When exporting photos for print, you often need pixel dimensions that match a specific print size (inches) at a chosen DPI (dots per inch).

5. Signage, Posters, and Banners

Large-format prints like posters or digital signage often start in inches but need pixel-perfect resolution for screen or print previews.

At our agency, these conversions happen almost daily—especially when syncing digital campaigns with physical branding assets.

The Key Variable: Understanding PPI (Pixels Per Inch)

You can’t convert inches to pixels without PPI, because pixels are relative to resolution.

What is PPI?

PPI (Pixels Per Inch) defines how many pixels are packed into one inch of a display or digital image.

• 96 PPI – Default for web and CSS.

• 72 PPI – Legacy standard (older Apple monitors).

• 300 PPI – Professional print quality.

• 150 PPI – Often used for large prints or banners.

Example:
1 inch at 96 PPI = 96 pixels
1 inch at 300 PPI = 300 pixels

The difference is huge—and it’s why PPI matters.

The Inches to Pixels Formula

The conversion formula is simple yet essential:

This formula powers our tool behind the scenes. Let’s see it in action:

Example 1: For Web (96 PPI)

If you have a 5-inch design for a website:

So, 5 inches = 480 pixels at 96 PPI.

Example 2: For Print (300 PPI)

If you’re preparing a 5-inch print asset for high-quality output:

That’s 5 inches = 1500 pixels at 300 PPI.

As you can see, the conversion depends entirely on your target resolution (web vs print).

How to Use the Converter Tool?

Using our converter is as straightforward as it gets:

1. Enter the value in Inches
   → Type your desired size (e.g., 5 or 8.5 inches).

2. Select or Enter the PPI
   → Choose from presets (72, 96, 150, 300) or input a custom value.

3. Instant Conversion
   → The tool instantly calculates the pixel equivalent based on your chosen PPI.

4. Copy Your Result
   → Use the “Copy” button to paste directly into design tools or specs.

Whether you’re resizing a digital image or aligning print mockups, the result updates in real time—no formulas, no confusion.

Advantages and Use Cases (Founder’s Perspective)

From my experience running a creative agency, every detail counts. Even a small mismatch in print or web sizing can lead to expensive mistakes or visual inconsistencies.

Here’s why we built and use this converter internally:

• Saves Time: Converts in milliseconds — no manual calculations or spreadsheets.

• Ensures Precision: Pixel-perfect accuracy, especially when scaling between print and digital.

• Team Consistency: Everyone (designers, devs, clients) sees the same measurement values.

• Client Communication: We can explain exactly why a 4-inch image equals 384px on the website.

• Cross-Medium Confidence: Helps when exporting assets for both web display and print production.

It’s a small tool that saves hours and guarantees consistency — from digital campaigns to billboard layouts.

Best Practices for Inches to Pixel Conversion

1. Always Confirm the Target Medium

• For web: Use 96 PPI.

• For print: Use 300 PPI (or as specified by your print vendor).

• For large format prints: Sometimes 150 PPI is sufficient.

2. Don’t Assume “1 Inch = 96 px” Always

That’s only true for web/CSS defaults. Retina screens and printers vary widely—always specify PPI.

3. Round Smartly

If you get decimals like 1259.88px, round appropriately—e.g., 1260px—for cleaner design workflow.

4. Understand DPI vs PPI

• PPI = pixels per inch (screens).

• DPI = dots per inch (print).
  Both affect visual sharpness but apply to different outputs.

5. Use Companion Tools

Conversions don’t stop here — use PX to Inches, CM to PX, and MM to PX tools to stay consistent across all units.
