Build clear partition takeoffs with flexible inputs and unit options. Choose drywall or masonry, include openings, add waste, then download results.
| Scenario | System | Length | Height | Openings | Waste | Key output |
|---|---|---|---|---|---|---|
| Office corridor | Drywall single | 40 ft | 10 ft | 1 (3x7 ft) | 10% | Boards 27 sheets, Studs 31 |
| Store room | Drywall double | 25 ft | 9 ft | 1 (3x7 ft) | 12% | Boards 34 sheets, Screws 1700 |
| Service partition | Masonry block | 30 ft | 10 ft | 0 | 8% | Blocks 244, Mortar 26 bags |
Example quantities are indicative. Real takeoffs depend on framing layout, board orientation, corner details, and specified reinforcement.
This calculator uses simplified rules-of-thumb to speed estimating. Always align with project specifications and approved methods.
Partition work sits at the intersection of schedule, cost, and quality. A small measurement error can multiply across dozens of rooms, causing board shortages, extra deliveries, or wasted labor. This calculator helps you build a repeatable method: start with geometry, remove openings, apply waste, then convert area into practical materials like sheets, studs, tracks, screws, finishing compounds, and tape. For masonry partitions, it estimates block quantities, mortar, and simplified reinforcement lengths to support early budgeting.
Begin by selecting the correct partition system. Drywall partitions vary by performance requirements: fire rating, acoustic targets, impact resistance, and moisture exposure. Double-layer board increases material and finishing needs, while also improving sound and fire performance when detailed properly. Masonry partitions often serve service areas and shafts, where durability and security are priorities.
Use centerline lengths from the plan and clear heights from elevations or reflected ceiling drawings. Subtract openings by entering a typical door size and quantity. If openings vary, use the weighted average width and height. This creates a reliable net area that can be checked against your drawing scale and room count.
Waste is not only breakage. It also covers offcuts, board orientation constraints, corner returns, and layout changes. For drywall, 8–12% is common on straightforward work; complex layouts, tight access, or phased construction may require more. For masonry, include cuts, damaged units, and bonding pattern adjustments.
Drywall sheets are calculated from net area multiplied by the number of faces and layers, divided by sheet area, then rounded up. Stud count is estimated from spacing and wall length, including end studs. Track length includes top and bottom runs, with a deduction at openings. Consumables scale from boarded area, letting you tune screws, compound, and tape rates to match your standard details.
Example: a corridor wall 40 ft long and 10 ft high with one 3×7 ft door, 10% waste, single-layer each side, 4×8 boards, and 16-inch stud spacing. Net area is 379 ft² per face (400 − 21). Boarded area is 758 ft² for two faces, and 834 ft² with waste. With 32 ft² per sheet, the estimate yields 27 sheets. Studs are 31 pieces, and tracks are roughly 77 ft after allowance. These numbers are starting points for procurement.
Use the output to create line items: boards, framing, insulation, and finishing materials. Cross-check studs against corners, tees, jamb studs, and control joints. For masonry, confirm reinforcement with structural notes. Always align with specifications for board type, thickness, and fire-rated assemblies.
Before ordering, reconcile the estimate with shop drawings or marked-up plans. Confirm ceiling conditions, head-of-wall details, and any backing requirements for fixtures. Update waste if the work is split across floors or if storage is limited. Consistent estimation improves forecasting and reduces costly surprises on site.
Use net area to remove openings, then add waste. Gross area is helpful for quick checks, but net area plus a realistic waste factor produces more reliable purchase quantities.
For simple runs, 8–12% often works. Increase waste for many corners, short segments, staggered schedules, or restricted access. Always match your contractor’s historical data when available.
Extra layers add handling time, more fasteners, and more finishing work. You may also need longer screws, different patterns, and additional compound and tape depending on the system requirements.
It is a planning estimate based on spacing and length. Real counts change with corners, intersections, jamb studs, headers, deflection track, and bracing. Adjust after reviewing the partition layout.
Use the average door size or input the most common opening. For mixed conditions, run the calculator multiple times and combine totals, or compute a weighted average opening area.
No. Reinforcement, grout, and mortar requirements depend on structural notes and code. Use the masonry results for early budgeting, then revise using engineered reinforcement schedules.
Yes, if you convert the wall path into an equivalent total length. For many small segments, increase waste and verify framing complexity, because cutting and alignment losses typically rise.
Measure carefully, check drawings, and confirm quantities before ordering.
