Pixels to Print Size Calculator

Do you have a digital image and want to know how large you can print it without losing quality? Our Pixels to Print Size Calculator is designed to help you find the perfect print size for your image, based on its resolution and desired DPI (dots per inch). Whether you're printing a photo, designing a poster, or preparing artwork, knowing the right dimensions in inches or centimeters is essential for quality results.

We’ve built this online tool so users like you can easily calculate pixels to print size with just a few clicks. It gives you fast and accurate results with helpful quality indicators, unit conversions, and resolution suggestions.

How Does Pixels to Print Size Work?

Every digital image is made of pixels. But when you print it, you're working with physical dimensions – inches, centimeters, or millimeters. The key to converting pixels into a printable size is DPI, or dots per inch. This defines how many pixels are packed into one inch of printed space.

Here's the basic calculation formula used:

Print Size (in inches) = Pixel Count ÷ DPI

For example, if your image is 2400 × 3000 pixels, and you want to print it at 300 DPI (standard photo quality), the calculation would be:

Width = 2400 ÷ 300 = 8 inches

Height = 3000 ÷ 300 = 10 inches

This means your image will print perfectly at 8x10 inches at 300 DPI.

How to Use the Pixels to Print Size Calculator

Using our calculator is incredibly simple:

1. Enter the pixel width and height of your image.
2. Choose your desired DPI (dots per inch) – for example, 300 for high-quality photo prints.
3. Select the unit you want the output in – inches, centimeters, or millimeters.
4. Hit calculate and instantly get your print size, along with conversion options and quality indicators.

You can also reverse the process to calculate the required pixels for a specific print size or find out the DPI of an existing image-to-print setup.

What Resolution Do I Need for a 16x20 Print?

For a 16x20 inch print, the resolution you need depends on the quality you want:

For photo quality (300 DPI):

• 16 × 300 = 4800 pixels wide
• 20 × 300 = 6000 pixels tall

So you need an image that’s 4800 × 6000 pixels.

For standard quality (150 DPI):

• 16 × 150 = 2400
• 20 × 150 = 3000

You need at least 2400 × 3000 pixels for an average print.

How Many Pixels Should an 8x10 Print Be?

At different resolutions, here's what you need:

• 300 DPI: 8 × 300 = 2400 pixels, 10 × 300 = 3000 pixels → 2400 × 3000
• 200 DPI: 8 × 200 = 1600, 10 × 200 = 2000 → 1600 × 2000

If you're printing close-up or professionally, always aim for 300 DPI.

What is the Pixel Size of an 8.5 x 11?

An 8.5 × 11 inch sheet is a standard US Letter size. Here's what you need:

• 300 DPI: 8.5 × 300 = 2550, 11 × 300 = 3300 → 2550 × 3300 pixels
• 150 DPI: 8.5 × 150 = 1275, 11 × 150 = 1650 → 1275 × 1650 pixels

Use 300 DPI for photo prints, 150 DPI for general documents or posters.

How Many Pixels is a 4x6 Print?

The 4x6 print is one of the most common photo sizes.

• 300 DPI: 4 × 300 = 1200, 6 × 300 = 1800 → 1200 × 1800 pixels
• 200 DPI: 4 × 200 = 800, 6 × 200 = 1200 → 800 × 1200 pixels

To keep your 4x6 photos sharp, always go with at least 1200 × 1800 pixels.
