Understanding your result
The headline is the total weight of the order, and the line under it gives the board, the sheet size and the weight of one sheet. The tiles give the weight per sheet, per square foot and, if you entered a payload, the trips and the sheets per trip.
The bars compare every board type at the sheet size you chose, which is the useful view when deciding between regular and lightweight board, or when a delivery has to come up stairs. The table shows the arithmetic: sheet area times weight per square foot, times the number of sheets.
The notes give the load the stack puts on the floor under it. For deliveries, lifts and their costs, the delivery and lift planner takes it from here; which board a surface needs is on the thickness selector; and the ceiling count with its weight is on the ceiling calculator.
How we calculate this
The weights per square foot are typical manufacturer figures, collected on the sheet sizes and weights table: 1.2 lb for 1/4 in, 1.4 for 3/8 in, 1.6 for 1/2 in regular, 1.25 for 1/2 in lightweight (USG’s published figure for its UltraLight panel), 1.7 for 1/2 in moisture-resistant, 2.2 for 5/8 in type X, 1.75 for lightweight type X and 2.5 for abuse-resistant 5/8 in. Trips use 90% of the payload you enter, leaving room for the driver and the tie-downs.
The assumptions behind the numbers
| Board | lb per sq ft | Where it comes from |
|---|---|---|
| 1/4 in regular | 1.2 | Typical manufacturer data |
| 3/8 in regular | 1.4 | Typical manufacturer data |
| 1/2 in regular | 1.6 | Typical manufacturer data (USG, CertainTeed) |
| 1/2 in lightweight | 1.25 | USG Sheetrock UltraLight product data |
| 1/2 in moisture-resistant | 1.7 | Typical manufacturer data |
| 5/8 in type X | 2.2 | Typical manufacturer data |
| 5/8 in lightweight type X | 1.75 | Manufacturer data (about 56 lb per 4 × 8 sheet) |
| 5/8 in abuse-resistant | 2.5 | Typical manufacturer data |
| Payload use | 90% | Our margin for driver and tie-downs |

Weights vary between brands and with moisture: board stored outside or in a damp basement gains weight. The calculator does not check your floor’s capacity, which only the structure’s design can do; it gives the load so you can spread it. How to move, store and lift board safely is in the weight and handling guide; which thickness a surface needs is in the thickness guide.
Two worked examples
A 58 sheet basement order of 1/2 in 4 × 8, a 1,600 lb pickup
- Per sheet: 32 × 1.6 = 51.2 lb
- Total: 58 × 51.2 = 2,970 lb
- Per trip: 1,600 × 0.9 ÷ 51.2 → 28 sheets; trips: 3
Three trips, each 1,400 lb, and every sheet carried down the basement stairs by hand. A boom delivery through a window well is often cheaper than the afternoon.
24 sheets of 5/8 in type X, 4 × 12, for a garage ceiling
- Per sheet: 48 × 2.2 = 105.6 lb
- Total: 24 × 105.6 = 2,534 lb
At over 100 lb a sheet, two people carry each one and a panel lift puts it on the ceiling; lightweight type X would bring each sheet to about 84 lb.
Where to find your inputs
Sheets. From your order or the sheet calculators.
Board. The thickness and type on the order; “lightweight” and “type X” are printed on the sheet edge.
Payload. On the sticker inside the driver’s door: the payload, or the gross vehicle weight minus the empty weight.
Common mistakes
- Overloading the truck. Payload includes the driver. Stay under it.
- One big stack on a long span. Spread it near walls and bearing points.
- Carrying 5/8 in board alone. Two people for anything over about 70 lb.
- Board stored flat on a damp floor. It soaks up water and warps; stack it on spacers.
- Ignoring the stairs. Long sheets do not turn tight corners. Plan the route.
- Assuming all 1/2 in board weighs the same. Lightweight is a quarter lighter.
Questions people ask
- How much does a sheet of drywall weigh?
- A 4 × 8 sheet of 1/2 in regular board weighs about 51 lb (1.6 lb per sq ft). Lightweight 1/2 in is about 40 lb. A 4 × 8 sheet of 5/8 in type X is about 70 lb, and a 4 × 12 sheet of 5/8 in about 106 lb. Brands differ by a few percent.
- How much does a 4 × 12 sheet of drywall weigh?
- About 77 lb in 1/2 in regular board, 60 lb in lightweight 1/2 in, and 106 lb in 5/8 in type X. At those weights, a ceiling of 4 × 12 sheets is a lift job.
- How many sheets of drywall can a pickup carry?
- Divide the truck's payload by the sheet weight, and leave some margin. A half-ton pickup rated for 1,600 lb carries about 28 sheets of 1/2 in 4 × 8 board at 90% of payload, or about 20 sheets of 5/8 in. Twelve-foot sheets overhang the bed and need a flag.
- Is lightweight drywall worth it?
- For DIY and for ceilings, often. It is about a fifth to a quarter lighter, so a 4 × 8 sheet of 1/2 in drops from about 51 to about 40 lb, and it scores and snaps the same way. It costs a little more per sheet, and type X and moisture-resistant versions exist.
- Can a floor hold a stack of drywall?
- A delivery of 50 sheets of 1/2 in 4 × 8 board weighs about 2,560 lb on 32 sq ft of floor, about 80 lb per sq ft, twice the typical design live load for a residential floor. Spread large deliveries in several stacks near walls and bearing points rather than in the middle of a span.
- Why is 5/8 in type X so much heavier?
- It is thicker, and its core includes glass fibres that hold it together in a fire. At about 2.2 lb per sq ft it is a third heavier than 1/2 in regular board. Lightweight type X boards are about 1.75 lb per sq ft.
