Business Card Aspect Ratio Calculator

Use this business card calculator to set card dimensions by region and maintain safe margins for trim and bleed.

Business cards vary by region, so ratio mismatches can affect logo placement and text spacing. Starting with the correct ratio and bleed zone prevents clipping and improves print reliability.

Practical Tips

  • Include bleed beyond trim and keep text inside a safe margin.
  • Export print-ready PDF or printer-approved raster format at 300 DPI.
  • Check regional standard size before sending to production.

Final quality depends on ratio planning, safe margins, and destination-specific exports. Use one master source file and generate each output ratio deliberately to keep typography, spacing, and visual hierarchy intact.

For mixed teams across marketing, design, and production, a shared ratio workflow reduces approval loops and improves consistency.
