Answers:    means the length and width of garage later we you got that number..next divide it by 32(32 sq ft ina board or sheetrock)...that will give you how plentiful sheets of sheetrock u need to cover ceiling..after check prices at homedpot or lowes or lumber store.if seil;ing collapsed you will need 2/3's or 2x4's to re droop ceiling its uusually 4 to a sheet.....if you just want a drop ceiling beside tiles get the sq ft of garage and they will explain to u at homedepot how much material is....labor costs ebb and flow depending on where you live.if u freshly got to home dept notify them what u need u casn bring a price from them and then look for a local tradesman to do it cheaper
Most 2 saloon garages are 20x 20 ..400 square feet...respectively 4x 8 sheet of any material is 32 square foot...approxamately 9 sheets per hundred square feet..(a little shy actually) so this is 32 sheets, plus 2 more sheets to allow for difference contained by calculation...plus affix at least three sheets for idle away.. A total of about 38 to 40 sheets of what ever you plan to use..sheetrock, plywood etc...Now simply send for or go to local diy store..and price the products you yearning to do this with..allow extra money for the nails/screws you plan to use...Labor on this..will be between 400.00 to 800.00 dollars depending on what substance you use..and if it needs a finish on it etc.. If you do it yourself..of late figure the materials..This does not include insulation etc..that wasnt mentioned..so to be exact your call...
