How many millimeters equal 1 pica?

4.233 mm = 1 pica. So conversely, 1 mm ≈ 0.236 picas. Use 1 pica as your reference: it's about 4.2 millimeters.

My metric spec says 20 mm. What's that in picas for InDesign?

20 mm × 0.236 ≈ 4.72 picas. Enter 4.72p in InDesign's measurement fields for precise setup.

Why convert to picas instead of just using millimeters in InDesign?

InDesign works in multiple units (inches, mm, cm, picas). Using picas aligns with typography (where points/picas are standard), making calculations with type sizes easier.

What's the relationship between picas and millimeters?

1 pica = 12 points. Since 72 points = 1 inch = 25.4 mm, then 1 pica ≈ 4.233 mm. Picas are the bridge between typography and physical measurement.
