work-station layouts:
• Distance between operators: 122 to 152 centimeters (48 inches to 60
inches) preferred.
• Leg clearance while seated, minimum:
Width: 61 centimeters (24 inches)
Depth: 46 centimeters (18 inches)
Height: 64 centimeters (25 inches).
• Toe clearance for standing: 10 centimeters (3.9 inches) minimum.
• See-over height (top of display unit to floor):
Standing operator: 140 centimeters (55 inches) maximum.
Seated operator: 100 to 11 0

distributed over the work area. The intensity of the light can be measured by
a common luminance meter.
