Sixteenths turns tape-measure math into instant answers. Type 12' 6-3/4" the way you say it, get exact fractions back, and cut it right the first time. Built for carpenters, framers, electricians, remodelers, and anyone who thinks in feet and inches.
Stop scribbling math on drywall. Stop trusting a phone calculator that turns 3/16" into 0.1875 and rounds your cut wrong. Sixteenths does construction math the way the trades actually work — try it free, and keep it on whatever terms suit you.

NEW: CONDUIT BENDING
Offsets, 90° stubs, 3- and 4-point saddles, and rolling offsets. Every mark is measured from the conduit end in sixteenths and tells you what to line up on the bender: arrow or rim notch. Multipliers and take-ups come straight from the Klein and Greenlee charts, for 1/2" to 1-1/4" EMT at 10° to 60°.
MORE ACCURATE STAIRS
Stringer length, incline angle, and stairwell opening now follow standard per-step layout, the same way Construction Master does it. Some results may differ slightly from the last version. The new numbers are the correct ones.
SHARPER ROOF LAYOUT
On irregular hips, the max jack spacing now goes to the steeper side, so neither side ever lays out wider than your OC.
SMOOTHER EVERYWHERE
• Menus and settings open at the right height every time, not tucked under the status bar
• Very large spans and rises no longer slow or stall the stair and baluster drawings
• Ask to Buy and pending purchases now say exactly what's happening
