depends on the table size- you need to know the length of the table you are making it for- if you want it to go the full length, or only in center, with an overhang...table runners are made in what ever size works for the table being used. I have an aunt who likes hers to hang over the sides- on one table and fit the center- leaving room for placemats on the other table. you can make your table runner any size you want- there is no real ''standard'' - even in stores you can find them ranging from about 30" on up to 72" or longer; and 14"- 30" wide.
