Read these tips and instructions on how to install drywall. Following these instructions can help you to save time and effort and end up with a neater job.
1. ESTIMATING MATERIALS NEEDED
Fig. 1 provides a chart for estimating the number of 4x8 sheets of drywall required for paneling rooms of various sizes. If wallboards of any other size are used, make the necessary adjustments.
Fig. 1  
How to Figure a Room for Drywall  
Determine the perimeter. This is merely the total of the widths of each wall in the room. Use this conversion table to figure out the number of wallboards needed.  
Perimeter  No. of 4x8 Wallboards Needed 
36'  9 
40'  10 
44'  11 
48'  12 
52'  13 
56'  14 
60'  15 
64'  16 
68'  17 
72'  18 
92'  23 
For example, if your room walls measure 14'x14'x16'x16', this equals 60' or 15 wallboards required. To allow for areas such as windows, doors, fireplaces, etc., use the deductions listed below:  
door = 1/3 wallboard(A)  
window = 1/4 wallboard (B)  
fireplace = 1/2 wallboard (C)  
Thus, the actual number of wallboards for this room would be 13 pieces (15 pieces minus 2 total deductions). Always use the nexy highest number of wallboards when the perimeter total is between ranges shown in the table. These figures are for rooms with 8' ceiling heights or less. 
2. ADVANCE PLANNING FOR DRYWALL
INSTALLATION
Always start by making a sketch of the wall and ceiling areas to be covered before applying the drywall.

3/8", 1/2"  1 5/8" coated type drywall nail  5 1/4 lbs. 
5/8"  1 7/8" coated type drywall nail  5 1/4 lbs. 
ESTIMATING JOINT COMPOUND AND TAPE

300400 sq. ft.  2 gals.  3  60' rolls 
500600 sq. ft.  3 gals.  1  250' roll 
700800 sq. ft.  4 gals.  1  250' 1  60' roll 
9001,000 sq. ft.  1 5 gal. pail  1  250' 2  60' rolls or 1  500' roll 
*A powder joint compound is also available. Estimate 60 lbs. per 1,000 sq. ft. of wallboard.
