| | 14 and 16 pins | 20 pins | 24 pins |
|---|---|---|---|
| Body length | 4.9 to 5.1 | 6.4 to 6.6 | 7.7 to 7.9 |

For every pin count:

- body width 4.3 to 4.5, lead tip to tip 6.2 to 6.6
- height 1.2 max, standoff 0.05 to 0.15
- pitch 0.65
- lead width 0.17 to 0.30, foot 0.50 to 0.75, lead thickness (0.15) reference

The model uses the middle of each range. Height is the 1.2 max, so read it as an envelope.

**Proportions, for looks only:** the gull wing's bend heights and the pin-1 mark.

Other TSSOP widths (3, 6.1 and 8 mm), other pin counts and exposed-pad versions aren't here yet; see `COVERAGE.md`.
