Aspect Ratio Calculator
Calculate proportional dimensions while maintaining aspect ratio. Perfect for resizing images, videos, or any content where proportions matter.
This free tool helps you calculate new dimensions while maintaining the original aspect ratio. Perfect for resizing images, videos, or any content where keeping the correct proportions is important.
How This Tool Works
Our aspect ratio calculator helps maintain proportions when resizing:
- Enter Original Dimensions - Input the current width and height
- Choose Lock Dimension - Select which dimension to lock (width or height)
- Enter New Size - Input the desired size for the locked dimension
- Get Results - See the calculated dimension, ratio, and scale percentage
The tool automatically maintains the original proportions to prevent distortion.
Frequently Asked Questions
What is aspect ratio?
Aspect ratio is the proportional relationship between width and height. Common ratios include:
- 16:9 - Standard widescreen video
- 4:3 - Traditional TV/monitor format
- 1:1 - Square format (common in social media)
- 3:2 - Common digital camera ratio
Why maintain aspect ratio?
Maintaining aspect ratio prevents distortion and keeps content looking natural. This is especially important for:
- Professional photography
- Video production
- Web design
- Print materials
How accurate are the calculations?
Our calculator provides pixel-perfect accuracy, rounding only when necessary to maintain whole pixels. The aspect ratio is preserved to three decimal places for maximum precision.
Tips and Best Practices
For best results:
- Use exact pixel measurements for most accurate results
- Lock the more important dimension for your use case
- Consider standard aspect ratios for specific platforms
- Remember that some platforms may crop your content
