A drop match is a pattern in vinyl sheet flooring that repeats diagonally across the sheet.
With products that have a drop match, each corresponding pattern element drops down the length (machine direction) of the material a specific distance, as the pattern repeats across the width.
Follow the pattern matching/estimating instructions outlined in the Armstrong Guaranteed Installation Systems manual, F-5061, in section XI, Estimating. When estimating a pattern with a drop match, the drop amount must also be added to each piece.
(Example: If room is 15’9″ in length and the material had an 18″ match with a 9″ drop, the first piece would be cut 16′, the second piece normally cut 16’6″ would now need to be cut 17’3″ after adding the drop match.)
