1. What is an Image Size Ratio Calculator?

Definition: This calculator computes the ratio between two dimensions of an image or any other object.

Purpose: It helps designers, photographers, and developers maintain proper aspect ratios when resizing images or designing layouts.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \text{ratio} = \frac{\text{size1}}{\text{size2}} \]

Where:

Explanation: The ratio is calculated by dividing the first dimension by the second dimension.

3. Importance of Size Ratio Calculation

Details: Maintaining proper aspect ratios is crucial for preventing image distortion, creating responsive designs, and ensuring visual consistency across different platforms.

4. Using the Calculator

Tips: Enter both dimensions in the same units. The second dimension must be greater than zero. The result is a unitless ratio.

A: Common ratios include 4:3 (standard), 16:9 (widescreen), 1:1 (square), and 3:2 (35mm film).

Q2: How do I use this ratio to resize an image?
A: Multiply either dimension by the ratio to calculate the corresponding dimension while maintaining aspect ratio.

Q3: Can I use different units for size1 and size2?
A: No, both dimensions must be in the same units for the ratio to be meaningful.

Q4: What does a ratio of 1 mean?
