How much flooring will you need for a 16' by 28' room?

High, My name is Brett_old carpenter. 16x28=448 448/32=14 That is if you are using 4'x8' sheets. You will need 14 sheets of 4'x8' Your square footage is 448sf. I have the feeling you are asking about laminated flooring that comes in a package of 25.64SF. If so:448/25.64=17.472 in other Words 18 packages. Always get more than you need, the alternative is worse.
