Door Acceptance & Tolerance Checker
Enter the measured gaps, frame plumb and how the door operates — and get an accept / snag / reject verdict with a readiness %. Basis: IS 1200 / CPWD workmanship; fire doors held to ≤3 mm.
What you measured
Operation & finish
Everyday internal door — even 2-4 mm margins, comfortable floor clearance for flooring/carpet. Targets are the accept ceiling; between target and the reject limit is a snag. Indicative India 2026 — confirm against your contract spec and a qualified site engineer.

Acceptance breakdown
Each criterion graded against its accept target and reject limit for a internal flush door.
Settle the snag list
DesignAI reviews your measured gaps and operation against acceptance criteria, and drafts a fair snag list to hand your fitter before sign-off.
How the verdict works
Each numeric margin is graded against an accept target and a reject limit; operation and finish are pass/fail. The worst single result sets the overall verdict — any reject makes the door a reject, any snag makes it a snag. The readiness % is a weighted average where accept = 100%, snag = 50%, reject = 0%. Typical workmanship holds margins to even 2-4 mm and frame plumb to ±1.5-2 mm (IS 1200 / CPWD basis); fire doors are tighter — gaps must stay ≤3 mm for the seals to perform, and a fire door that does not self-close is an automatic reject.
This is an indicative QA aid — confirm with your carpenter / fitter on site and, for fire and accessible doors, a qualified site engineer against your contract spec, NBC / IS 3614 and RPwD lever heights. It is not a substitute for certified inspection or the tested fire-door set. Where hardware or rectification is priced, note that material and labour attract 18% GST, and rectify accepted snags within the defect-liability period (commonly 6-12 months in India).
