TO
GLOSSARY

Brief Definition

Use this reference to convert between common aspect ratios and understand how to adapt creative non-destructively.

Understanding ratio conversion

Ratios describe shape, not pixel count; you can express the same ratio at multiple resolutions. When converting, decide whether to fit (preserve all content with padding/extension) or fill (crop) based on the placement’s needs.

Why a calculator matters

Choosing ratios confidently speeds production and reduces errors. A calculator clarifies which exports you need for coverage and prevents low-quality letterboxing.

  • Ensures correct exports per placement
  • Prevents avoidable crops and UI conflicts
  • Standardizes production across teams

How to Convert

  • Choose the target ratio by placement
  • Use fit (padding/extension) to avoid cropping important content
  • Reposition text and logos within safe zones per ratio

Key Takeaways

  • An aspect ratio calculator helps convert between width:height formats for different placements.
  • Choose fit (padding) over fill (crop) to preserve important content when converting ratios.
  • Build an export checklist for common ratios (1:1, 4:5, 9:16, 16:9) tied to your active placements.
  • Store templates with safe-zone guides to speed production and reduce QA cycles.
