Vinyl Flooring Calculator
Sheet vinyl comes off a roll of a fixed width, so buying it is a cutting problem rather than an area divided by a box coverage. Give the room size and the roll width and this works both orientations, reports the cheaper one with the strip count, the linear feet and yards, where the seams land and how much is left over, and puts the other way round beside it so the choice is visible. A second mode covers the glue-down side, with adhesive by the gallon from the spread rate on your own pail, the pails to buy, and what changes when the floor is loose laid or click lock instead. For plank layout, stagger and the last row width, the laminate flooring calculator does that arithmetic already.
