Image Aspect Ratio Calculator

Calculate the aspect ratio of images, determine required dimensions, and understand image proportions

Input Parameters

Calculation Results

Aspect Ratio

Aspect ratio: N/A

Where:
Aspect Ratio = Width ÷ Height

New Dimensions

Width: N/A px
Height: N/A px

Based on maintaining the original aspect ratio

Required Size for Specific Ratio

For 16:9: Width = N/A px, Height = N/A px
For 4:3: Width = N/A px, Height = N/A px
For 1:1: Width = N/A px, Height = N/A px

Enter your target width or height to calculate the other dimension

Learn how to use the Image Aspect Ratio Calculator and understand image dimensions

How to Use the Calculator

  1. Enter the width and height of your image in pixels in the input fields.
  2. Click the "Calculate" button to see the results.
  3. The calculator will display the aspect ratio of your image.
  4. You can also see what new dimensions your image would have if scaled to maintain the original aspect ratio.
  5. The "Required Size for Specific Ratio" section shows what dimensions your image would need to be if you wanted to use a standard aspect ratio like 16:9, 4:3, or 1:1 (square).

Understanding Aspect Ratio

Aspect ratio is the proportional relationship between an image's width and height. It's expressed as width:height. Common aspect ratios include:

  • 4:3 - Traditional TV and computer screen ratio
  • 16:9 - Widescreen TV and computer screen ratio
  • 1:1 - Square images (common in social media profiles)

Common Use Cases

  • Determining if your image will fit in a specific frame or container
  • Resizing images while maintaining their proportional appearance
  • Creating images for different platforms with the appropriate dimensions
  • Designing graphics that need to maintain their shape across different uses

Formula Explanations

Aspect Ratio = Width ÷ Height

New Dimensions = Original dimension × (New dimension ÷ Original dimension)

Required Size for Specific Ratio = Target dimension × (Ratio ÷ Other dimension)
