How to Use This Calculator

Enter Wall length (ft), Wall height (ft), and Drywall layers (0=single, 1=double).
Set Stud spacing (0=16, Insulation (0=no, 1=yes), and Waste allowance (%).
Review Drywall sheets (4x8), Metal studs, and Total material cost ($) ($).
Use Wall area (sq ft) and Track (LF) to inform your decision.

How the result changes with Wall length (ft)

Wall length (ft)	Drywall sheets (4x8)	Metal studs	Total material cost ($)
51	32	40	$2,120.56
176	109	133	$7,193.76
325	202	245	$13,278.80
450	280	339	$18,381.65

What each input means

Wall length (ft): Total linear feet of partition wall.
Wall height (ft): Floor-to-ceiling or floor-to-deck height.
Drywall layers (0=single, 1=double): Single layer (1-hr fire) or double layer (2-hr fire) each side.
Stud spacing (0=16" OC, 1=24" OC): 16" OC for standard, 24" OC for non-load-bearing or cost savings.
Insulation (0=no, 1=yes): Whether to include batt insulation in the stud cavity.
Waste allowance (%): Typical 10% for straight runs, 15% for complex layouts.

What each result means

Wall area (sq ft): One-side wall surface area.
Drywall sheets (4x8): Total 4'x8' drywall sheets including waste and both sides.
Metal studs: Number of vertical studs needed.
Track (LF): Linear feet of top and bottom track.
Insulation bundles: Batt insulation bundles (~40 sq ft each).
Joint compound (gal): Gallons of joint compound for taping and finishing.
Tape rolls: 500-ft rolls of paper joint tape.
Drywall screws: Total drywall screws needed.
Est. STC rating: Estimated Sound Transmission Class for the assembly.
Fire rating (hrs): Estimated fire resistance rating in hours.
Total material cost ($): Estimated total material cost.

How this is calculated

Worked example, using the default values

Identify Input Parameters
4 parameters
Wall length (ft) = 30, Wall height (ft) = 9, Drywall layers (0=single, 1=double) = 0, Stud spacing (0=16 = 0 = 6 input(s) provided
Calculate Drywall sheets
Drywall sheets = ceil(sheetsNet * (1 + wastePct / 100))
19 = 19
Calculate Metal studs
Metal studs
24 = 24
Calculate Total material cost
Total material cost = drywallCost + studCost + insulationCost + finishingCost
1271.22 = $1,271.22
Calculate Wall area
Wall area = wallLengthFt * wallHeightFt
270 = 270
Calculate Track
Track = wallLengthFt * 2
60 = 60
