# 2.54 mm pin headers, 1×2 to 2×20, vertical and right-angle

> How tall is a 2.54 mm pin header and how much clearance does a jumper wire need?

- Category: Electronics › Connectors
- Kind: Standard part
- Basis: KiCad 3D models of standard 0.1 in (2.54 mm) male headers: 2.5 mm plastic base, 6.0 mm pin above, 3.0 mm below; row spacing 2.54 mm

## Notes

- Standard male header: plastic 2.54 mm square per position × 2.5 mm tall; pin 0.64 mm square, 6 mm above the plastic, 3 mm below. Total height above board 8.5 mm. A Dupont jumper housing adds 14 mm, so budget 23 mm over a header for cables.
- Row spacing 2.54 mm; a 2×20 Pi header is 50.8 × 5.08 × 8.5 mm. Right-angle headers extend 6 mm past the board edge at 2.5 mm height.
- Case clearance over a 1×n vertical header with nothing plugged in: 9 mm. Female stacking headers (sockets) are 8.5 mm tall with 2.54 mm pitch.

## Questions

**How tall is a 2.54 mm pin header?**

8.5 mm above the board (2.5 mm plastic + 6 mm pin); pins extend 3 mm below. With a Dupont jumper plugged in: about 23 mm.

**How wide is a 2x20 pin header?**

50.8 × 5.08 mm footprint, 8.5 mm tall; the Raspberry Pi GPIO header.

**What hole size for 2.54 mm header pins?**

Ø1.0 mm plated holes on a PCB; in a printed part, a 0.7 mm square pin needs a 0.9–1.0 mm hole for a press fit.
