HDHMR vs plywood for wardrobes
For the wardrobe box, pick plywood if you want a grade you can check on the quote: MR, BWR or BWP. For the doors, this example uses HDHMR, and we found no Indian standard or neutral test that ranks it above plywood.
Which board goes where
Example estimate. Warm colours are plywood. Blue is HDHMR.
Box board6 sheets
- Board
- 18 mm finished board (16 mm BWR plywood core + laminate on both faces)

Choose by part
Box (sides, top, floor, shelves)
For the wardrobe box, pick plywood if you want a grade you can check on the quote. Ask which grade: MR, BWR or BWP. This example uses BWR.
Doors
This example uses HDHMR. We found no Indian standard or neutral test that ranks HDHMR above plywood. Ask for the board's product sheet.
A part near water or a damp wall
Ask which board sits there. A plywood grade names how well its glue stands water.
Two questions
Ask which board sits near water, and ask for the board's product sheet.
Plywood vs HDHMR
| Plywood (box board) | HDHMR (door board) | |
|---|---|---|
| What it is | Thin wood layers (plies), glued with the grain of each layer crossed. | HDHMR is not plywood. It is a high-density, high-moisture-resistant board. |
| Can I check it on a quote? | Yes. Ask for the IS 303 grade: MR, BWR or BWP. | We found no Indian standard to check it against. Ask for the maker's product sheet. |
| What one maker states | The IS 303 grade is the check. | One maker states a density over 850 kg/m³. |
What we could not find
We found no Indian standard written for HDHMR itself, and no neutral test comparing it with plywood. So this page quotes no swelling, screw-holding or strength figures.
The standards and the counts
For the technical reader: what the standards say
IS 303:2024 grades general-purpose plywood MR, BWR or BWP, and rates bending strength in classes F10 to F50.
The 1989 edition named the grades boiling water resistant (BWR) and moisture resistant (MR), set by the bond strength of the glue between the veneers.
IS 303 requires the grain of adjacent plies to run at right angles to each other.
Marine plywood has its own standard — IS 710 — covering plywood for marine and river craft.
One maker states its HDHMR is made from hardwood with a density over 850 kg/m³, and lists door and kitchen shutters among its uses.
For your carpenter: how we count
The example is about 8 ft (2438 mm) wide and 7 ft 6 in (2286 mm) tall, with hinged doors and no loft.
The box board is boiling-water-resistant plywood; the door board is a high-density, high-moisture-resistant board.
Sheet counts assume 2440 × 1220 mm sheets, a 4 mm saw cut and 5 mm trim.
Single-job estimate — re-nest before cutting.
Every board in the example
- 18 mm box board
- 41 parts, 6 sheets
- 18 mm finished board (16 mm BWR plywood core + laminate on both faces); used for sides, floor, top, shelves, dividers, plinth, wall-fixing rails, drawer fronts and drawer boxes
- 20 mm door board
- 6 parts, 3 sheets
- 20 mm finished board (16 mm HDHMR core + face laminate and back balancer); used for doors and filler strips
- 8 mm back board
- 5 parts, 3 sheets
- 8 mm finished board (6 mm plywood core + laminate on both faces); used for backs and drawer bottoms
For wardrobe makers
In your workshop, each board can differ: core, faces and thickness for each part. The cut list and sheet counts follow those choices.

MR (commercial) vs BWR vs BWP plywood
Commercial plywood is often MR. IS 303 grades MR, BWR and BWP for water duty. A reference factory wardrobe puts BWR on the box alone; the doors are HDHMR.
