US customary measurements
Enter decimal feet, feet and inches, or common inch fractions. An unlabelled value such as 10.5 means 10.5 feet; use an inch label for values such as 10.5 in. Mixed measurements such as 8 ft 3 1/2 in are also supported. Clear opening width means the inside-face distance between posts.
Metric measurements
Use millimetres, centimetres, or metres, such as 2400 mm, 240 cm, or 2.4 m. The calculator normalizes measurements internally before solving.
Good field notes
- Sketch each straight segment.
