Plywood Calculator
Free plywood sheet calculator for Indian carpenters. Enter furniture size and material — get sheets needed with wastage, laminate area, hinges and material cost. No signup.
Every shelf, partition, drawer and shutter is cut as a real panel and packed onto sheets — so what goes inside changes the sheet count. Defaults are industry-standard starting points, not verified workshop figures.
About this calculator
This calculator sizes real furniture, not abstract sheet counts. Pick a furniture type and its dimensions, choose the material grade, and it works out how many 8×4 sheets you need after wastage, how much laminate area is involved, how many hinges the doors will take, and what it all costs at your rate. Solid wood can be costed by CFT or by square foot. It's the same engine that runs inside the GuniyaZed app.
Which standards this follows
Material grades follow Indian Standard codes — the same ones printed on the ply you buy.
- IS 303Plywood for general purposes — covers MR and BWR grades
- IS 710Marine plywood — the BWP grade
- IS 1659Block boards
- IS 12406Medium density fibreboard (MDF)
Frequently asked questions
How many plywood sheets do I need for a wardrobe?
It depends on size and depth, not just door count. A standard 2400×2100×600 mm three-door wardrobe in 18 mm ply typically needs around 8 sheets after wastage. Enter your actual dimensions above for your number.
What wastage percentage should I add?
This calculator builds a wastage allowance into its sheet count, so the number you see is already wastage-adjusted rather than a bare area figure. On simple boxy work real wastage can be lower; on irregular or curved work it goes higher. If you cut carefully with a cut plan, wastage drops.
What's the difference between MR, BWR and BWP plywood?
MR is moisture resistant — for dry indoor work. BWR is boiling water resistant — better for kitchens and bathrooms. BWP (marine, IS 710) handles the most water and costs the most. Pick by where the furniture will sit, not by budget alone.
Should I cost solid wood by CFT or square foot?
Timber is traditionally sold by CFT (cubic feet), and that's the default here. Some carpenters and clients prefer a per-square-foot rate at a fixed thickness. Both options are available — use whichever your supplier quotes in.
