How do I choose a table runner size?
For example, if you have a square or rectangular table that is 60 inches wide, your table runner width should be 20 inches. This will leave enough space on either side of the table so that your place settings don’t overlap with your runner. The length of your table runner is up to you.
Should a table runner hang over the table?
Typically, a table runner should hang over each side of the table where the ends fall. This is much more esthetically pleasing than a runner that stops where the table ends or is slightly shorter than the table. The amount of hang should be equal on both sides and can vary, just like the drop length of a tablecloth.
