Architrave & Door Trim Calculator

Enter the door or frame size, choose one face or both, and a ₹/rft rate — get the exact running-feet of architrave (3 sides per face — 2 jambs + head, mitred — plus 10% wastage) and the all-in cost with 18% GST. Indicative India 2026.

Your trim

Trim on both sides of the wall — the usual finish for internal & main doors in Indian homes. Seasoned hardwood casing; takes polish or paint well. Per face the trim runs 2 jambs + 1 head (mitred); no trim on the floor side. Wastage of 10% is added for mitre cuts and offcuts. Indicative India 2026 — varies by profile, finish and vendor.

DesignAI suggests an architrave profile, material and finish to match your doors and interior — and sense-checks the quantity and quote.

How this is worked out

Architrave (door casing) frames the door on the exposed face of the wall. Per face it runs the three sides of the opening — two jambs (the height) plus the head (the width) — mitred at the top corners; there is no trim on the floor/sill side. Choosing both faces doubles the length. We add 10% wastage for mitre cuts and offcuts, multiply by your ₹/rft rate, then add 18% GST where shown.

These figures are indicative — confirm with your carpenter/fitter on site, and measure twice before ordering. Standard sizes are used unless you enter a custom opening; site dimensions and a deeper trim profile can change the quantity. Order trim in full lengths so a single jamb has no joint. This is a planning aid, not a substitute for a skilled carpenter or site engineer.
