Most "free" casing calculators are rigid—you’re stuck with fixed dimensions and generic assumptions. That works for a closet, but it fails on real jobsites, where you're paint grade vs stain grade, juggling 1/6 to 3/0 doors, 8/0 heights, and custom architraves. When the math gets complicated, most online tools tap out, leaving you with expensive enterprise software as your only other option.
Built by installers for the field, it replaces the tape-and-notepad grind with high-performance logic.
CHIPTRIM evaluates your opening schedules using linear optimization algorithm, with heuristic bin packing and optimizes a cut plan for the highest possible physical yield. We don't just give you a total length; we provide a strategic ordering guide that accounts for tiered waste on a project scale, saw blade kerfs, and the reality of damaged stock ends. You get exactly the data you need to order the right amount of stock lengths—nothing more, nothing less.
CHIPTRIM will always value input and requests from our users. Since it’s built for pros, it will continue to be developed by them.
WHAT YOU ENTER (AND WHY)
CHIPTRIM only asks for what actually affects trim quantities. That’s on purpose.
You enter your door and window sizes + quantities like a normal takeoff.
Why this matters:
Casing is driven by perimeter math
Quantity drives totals and optimization
This tells CHIPTRIM your real trim face so it can handle allowances correctly and keep results consistent across different profiles.
Why we ask for it:
It affects how you think about coverage, reveals, and ordering
It keeps the tool usable across paint-grade and stain-grade work
This is the “real life” part—because trim isn’t installed like a perfect CAD drawing.
You might add a little extra per side because:
jambs aren’t always perfect
drywall isn’t always perfect
you want insurance against tight cuts
The Law of large numbers: Small jobs and big jobs behave differently.
On small jobs, one mistake is a big percentage
On big jobs, the optimizer has more flexibility and the buffer can be lower
CHIPTRIM applies a tiered buffer to help you order like a pro without guessing.
Instead of:
perimeter math
converting inches to feet
adding buffers
re-checking totals
You get a report in seconds. That means you can quote more jobs—or quote the same jobs with less stress.
Most casing waste comes from:
using the wrong stock length
cutting without a plan
not accounting for kerf
not grouping cuts
CHIPTRIM groups and optimizes cuts so you burn fewer sticks.
The best “profit margin” tool is avoiding:
last-minute delivery fees
sending a guy back to the supplier
ordering the wrong lengths
CHIPTRIM gives you a materials list and the confidence signals to back it up.
