Ready for Production?

Ensure your Figma designs are pixel-perfect for print. Use Printery to export high-fidelity PDFs with accurate color and dimensions.

Why Resolution Matters

Verify Print Quality

Check if your pixel dimensions produce 300 DPI. 2480px = 210mm at 300 DPI.

Match Printer Specs

Printers give specs in mm. Convert to pixels to create correct Figma frames.

Avoid Blurry Prints

Calculate effective DPI to ensure high-quality output for posters or cards.

Global Standards

Work with A4, A5, and A3 standards at proper resolution for international print.

Real-world Example

For a standard postcard (152.4 × 101.6mm), you need 1800 × 1200 pixels to achieve 300 DPI. Designing at this size ensures crisp, professional results.

1800 × 1200px = 300 DPI

Figma Print Workflow

1

Get Print Specs

Convert specs like 'A4 (210×297mm) at 300 DPI' to 2480×3508px.

2

Design in Figma

Create a frame at exact pixel dimensions. Keep safe margins for bleed.

3

Verify & Export

Use this tool to verify DPI, then export with Printery for perfect results.

Frequently Asked Questions

How many mm is 1000px at 300 DPI?

1000 pixels at 300 DPI equals 84.67 millimeters. Use the formula: MM = (Pixels ÷ DPI) × 25.4. This tells you the physical print size of your digital design.

Why does DPI affect px to mm conversion?

DPI determines how many pixels fit in a physical inch. Higher DPI means more pixels in the same space, resulting in a smaller physical size with higher detail.

What is effective DPI for print?

Effective DPI is the actual resolution when printed. 300+ DPI is excellent, 150-299 is acceptable for large prints, and below 150 is too low.

Perfect Exports
Every Time

Printery automatically verifies your designs meet 300 DPI standards and exports press-ready PDFs with CMYK and bleed.
