1. What is Image Resolution?

Image resolution refers to the total number of pixels in an image, calculated by multiplying the width in pixels by the height in pixels. It's a key factor in determining image quality and detail.

2. How Does the Calculator Work?

The calculator uses the resolution equation:

Where:

• \( pixels\textunderscore width \) — Width of the image in pixels
• \( pixels\textunderscore height \) — Height of the image in pixels

Explanation: The equation simply multiplies the width by height to get the total number of pixels in the image.

3. Importance of Resolution Calculation

Details: Knowing an image's resolution helps determine its quality, file size, and suitability for different uses (web, print, etc.).

4. Using the Calculator

Tips: Enter the width and height in pixels. Both values must be positive integers greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: What's considered high resolution?
A: For photos, typically 1 megapixel (1 million pixels) or more is considered high resolution.

Q2: How does resolution affect image quality?
A: Higher resolution means more detail, but also larger file sizes. The optimal resolution depends on the intended use.

Q3: What's the resolution of 4K images?
A: 4K resolution is typically 3840 × 2160 pixels (about 8.3 megapixels).

Q4: Does resolution equal quality?
A: While important, resolution is just one factor in image quality. Sensor size, lens quality, and compression also matter.

Q5: How does resolution relate to print size?
A: Print quality depends on both resolution and DPI (dots per inch). A 300 DPI print would be 10×6.7 inches from a 3000×2000 pixel image.
