Complete Guide to Canvas Aspect Ratios
What is Aspect Ratio?
Aspect ratio describes the proportional relationship between an image's width and height. It's expressed as two numbers separated by a colon (like 4:3) or as a decimal (like 1.33).
Common Aspect Ratios in Art
| Ratio | Decimal | Common Use | Example Sizes |
|---|---|---|---|
| 1:1 | 1.00 | Square format | 12×12, 20×20, 30×30 |
| 4:5 | 0.80 | Portrait standard | 8×10, 16×20, 24×30 |
| 3:4 | 0.75 | Classic portrait | 9×12, 18×24, 30×40 |
| 2:3 | 0.67 | 35mm photo | 12×18, 16×24, 24×36 |
| 5:7 | 0.71 | Common print | 5×7, 10×14, 15×21 |
Why Aspect Ratio Matters
- Framing: Standard frames match common aspect ratios
- Reproduction: Ensures prints maintain proper proportions
- Digital Display: Prevents distortion on screens
- Series Work: Creates visual cohesion in collections
- Gallery Display: Standardized sizes simplify hanging
Scaling Your Artwork
When scaling artwork, always maintain the aspect ratio to prevent distortion:
- Calculate the current aspect ratio
- Determine your target dimension (width or height)
- Calculate the corresponding dimension using the ratio
- Round to practical measurements
Tips for Choosing Canvas Ratios
For Portraits
- 3:4 or 4:5 ratios work well
- Vertical orientation typical
- Consider head and shoulder space
For Landscapes
- 3:2 or 16:9 for panoramic views
- Horizontal orientation preferred
- Wide ratios create drama
Frequently Asked Questions
How do I resize artwork without distortion?
Always maintain the same aspect ratio when resizing. Use this calculator to find the correct corresponding dimension when you change either width or height. For physical artwork, this might mean adding borders or cropping. For digital work, use "constrain proportions" in your software.
What aspect ratio is best for selling prints?
Standard ratios like 4:5 (8×10, 16×20), 3:4 (12×16, 18×24), and 2:3 (12×18, 24×36) are most commercial because they fit readily available frames. Creating artwork in these ratios makes it easier and more affordable for customers to frame their purchases.
