1. What is the Print Size Calculator?

The Print Size Calculator determines the maximum print size (in inches) you can achieve from a digital image based on its megapixel resolution and your desired print quality (DPI).

2. How Does the Calculator Work?

The calculator uses the following formula:

\[ \text{Print Size} = \sqrt{\frac{\text{Megapixels} \times 1,000,000}{\text{DPI}^2}} \]

Where:

\( MP \) — Megapixels of the image
\( DPI \) — Dots per inch (print resolution)

Explanation: The formula calculates the maximum print size by determining how many pixels are available per inch at your desired DPI.

3. Importance of Print Size Calculation

Details: Knowing the maximum print size helps photographers and designers ensure their images will maintain quality when printed at specific sizes.

4. Using the Calculator

Tips: Enter the camera's megapixel count and desired print DPI (300 DPI is standard for high-quality prints). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What DPI should I use for printing?
A: 300 DPI is standard for high-quality prints. 150 DPI may be acceptable for large format prints viewed from a distance.

Q2: How does megapixel count affect print size?
A: More megapixels allow for larger prints at the same DPI, or the same size prints at higher DPI.

Q3: Can I print larger than the calculated size?
A: Yes, but quality will decrease as the DPI drops below recommended levels.

Q4: Does this work for both width and height?
A: This calculates the maximum square print size. Actual print dimensions depend on your image's aspect ratio.

Q5: How does sensor size affect this calculation?
A: Sensor size affects image quality but not the maximum print size calculation, which depends only on pixel count.
