1. What is Aspect Ratio?

Definition: Aspect ratio is the proportional relationship between an image's width and height.

Purpose: It helps maintain consistent proportions when resizing images or videos across different devices and screens.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ AR = \frac{\text{width}}{\text{height}} \]

Where:

Explanation: The calculator divides width by height to get the aspect ratio, then simplifies it to the smallest whole number ratio.

3. Importance of Aspect Ratio

Details: Correct aspect ratio ensures images and videos display properly without distortion on different screens and platforms.

4. Using the Calculator

Tips: Enter the width and height in pixels (must be positive integers). The calculator shows both decimal and simplified ratio formats.

5. Frequently Asked Questions (FAQ)

Q1: What are common aspect ratios?
A: Common ratios include 16:9 (HD video), 4:3 (standard TV), 1:1 (square), and 21:9 (ultrawide).

Q2: How do I use the simplified ratio?
A: The simplified ratio (like 16:9) is useful for setting proportions when resizing or creating new content.

Q3: Does this work for non-pixel dimensions?
A: Yes, you can use any consistent units (inches, cm, etc.) as long as both dimensions use the same unit.

Q4: What if my aspect ratio is very large?
A: The calculator handles any positive dimensions, but extremely large ratios may indicate incorrect inputs.

Q5: How precise is the calculation?
A: The decimal ratio shows 4 decimal places, while the simplified ratio is mathematically exact.
