Drywall screw packs.

Apply the provided grid to each actual panel face, keeping boundary positions explicit.

Selected pack count and supplied horizontal and vertical fixing intervals.

Check this ordering assumption

A square-area rate is not identical to a grid with edge rows on every panel.

The page does not recommend screw spacing or fixing compliance.

This illustrative set of supplied inputs demonstrates Specified Drywall Panel Screw Grid Calculator. Replace the example measurements and product figures with your own before ordering.

Supplied input	Metric display	US display
Panel width	1.2 m	3.94 ft
Panel length	2.4 m	7.87 ft
Specified perimeter spacing	0.3 m	0.98 ft
Specified interior grid spacing	0.6 m	1.97 ft
Identical panels	10	10
Screws per box	100	100

Perimeter = 2 ceil(width / edge spacing) + 2 ceil(length / edge spacing); interior = (ceil(width / field spacing) − 1) × (ceil(length / field spacing) − 1).Count mathematical perimeter and interior screw positions on identical panels using your supplied grid, with corners counted once. Perimeter = 2 ceil(width / edge spacing) + 2 ceil(length / edge spacing); interior = (ceil(width / field spacing) − 1) × (ceil(length / field spacing) − 1).

Screw boxes for the supplied panel grid: 3 boxes

Perimeter positions per board: 24
Interior positions per board: 3
Total specified screws: 270 screws

This is a mathematical panel grid: corners counted once, interior positions at multiples of the supplied field spacing. It does not choose a fastening schedule, supporting member pattern or shared-edge fixings.
