What Is Aspect Ratio?
Aspect ratio describes the proportional relationship between an image's width and height. A 16:9 ratio means the width is 16 units for every 9 units of height.
Common Aspect Ratios for Rendering
| Ratio | Use Case |
|---|---|
| 16:9 | Widescreen displays, presentations, video |
| 4:3 | Traditional monitors, print layouts |
| 3:2 | Photography, DSLR sensor ratio |
| 1:1 | Instagram, social media thumbnails |
| 21:9 | Ultrawide, cinematic renders |
| 9:16 | Mobile stories, vertical video |
Example
A 3840 × 2160 render simplifies to 16:9. If you want a 4:3 version at 3840 px wide, the height would be 3840 ÷ 4 × 3 = 2880 px.
Frequently Asked Questions
- What aspect ratio should I use for architectural renders?
- 16:9 is the most common for presentations and portfolio images. Use 1:1 for social media, 9:16 for mobile/stories, and 3:2 or 4:3 for print-oriented work.
- What resolution should my architectural render be?
- For screen display, 1920×1080 (Full HD) or 3840×2160 (4K) at 16:9 works well. For print, calculate based on DPI — a 300 DPI A3 print needs about 4960×3508 pixels.
- How do I calculate aspect ratio from pixel dimensions?
- Divide both width and height by their greatest common divisor (GCD). For example, 1920÷120=16 and 1080÷120=9, giving 16:9.
