Humanform

Automotive

Use Humanform for the space around a driver or passenger: leg room, knee height, seated eye height, and reach to a control. The same measurements apply to other seated cabins, such as a cockpit or a control room.

Design Fit can load Cockpit fit: sitting eye height, knee height, shoulder breadth (biacromial), elbow-fingertip length, and leg room.

Command line

humanform-cli predict LegRoom --country US --gender male --age 40 --percentile 95
humanform-cli predict KneeHeight --country US --gender everyone --age-min 18 --age-max 70 --percentile 95
humanform-cli accommodate --pack cockpit --country US --gender everyone --age-min 18 --age-max 70 --target 90

accommodate requires Humanform Pro. The result is a Humanform preset, not a vehicle or aviation standard.

Check a cabin you have already dimensioned:

humanform-cli fit \
  --limit LegRoom,<lower>,<upper> \
  --limit KneeHeight,<lower>,<upper> \
  --limit SittingEyeHeight,<lower>,<upper> \
  --country US --gender everyone --age-min 18 --age-max 70

MCP

Use the Humanform accommodate tool with pack cockpit, country US, gender everyone, ageMin 18, ageMax 70, and target 90. Also predict LegRoom and KneeHeight at the 5th and 95th percentiles for the same population. Report millimetres. Say this is a Humanform preset, not a standards certificate.
