1. What is Print Size Calculation?

The print size calculation determines how large a 10 megapixel image can be printed at a given DPI (dots per inch) while maintaining quality. It helps photographers and designers understand the maximum print dimensions for their digital images.

2. How Does the Calculator Work?

The calculator uses the print size formula:

Where:

• 10 — Megapixels of the image (10,000,000 pixels)
• DPI — Dots per inch (print resolution)

Explanation: The formula calculates the linear print size by determining how many pixels fit per inch at the given DPI.

3. Importance of Print Size Calculation

Details: Knowing the maximum print size helps ensure image quality is maintained when printed, preventing pixelation or loss of detail.

4. Using the Calculator

Tips: Enter the desired print resolution in DPI. Common values are 300 DPI for high-quality prints, 150 DPI for acceptable quality, and 72 DPI for draft quality.

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between DPI and print size?
A: Higher DPI values result in smaller maximum print sizes because more dots are packed into each inch.

Q2: Why use 10 megapixels as the standard?
A: 10MP is a common resolution that provides a good balance between file size and image quality for many applications.

Q3: What DPI should I use for different print types?
A: 300 DPI for photo prints, 150-200 DPI for posters viewed from a distance, 72-100 DPI for large format prints like banners.

Q4: Does this work for non-square images?
A: The calculation gives the maximum square dimension. For rectangular images, you'll need to calculate based on the aspect ratio.

Q5: How does this relate to viewing distance?
A: Prints viewed from farther away can use lower DPI since the human eye can't resolve the individual dots at a distance.
