What To Use For a 4ft Rectangle Table?

Banquet tables are generally 30" wide and 30" high. To get a floor length cloth you add the width(30) plus the height x2(60) for a total width needed of 90". Do the same for the length : 48 plus 60 = 108". Therefore you need a cloth 90x 108 for floor length

Another option is to use a cloth that covers the top of the table and add banquet skirting. It is held on with clips, velcro or both.

Is it the kind of table where you WANT to have everything covered? I would factor that in when considering sweetheart table options. I would also suggest that you consider that it's different than any other table setting in the fact that you and your SO will be getting up and down and need something that won't construct you sitting or moving.

You can choose a narrower cloth so it is not floor length on the back side where you will sit = easier to get up and down.

You can use an overlay of any fabric you like letting it lay flat or swagging it at the front.

You can use a round cloth as an overlay.

You can use letters-LOVE- your initials etc

You can have a Cinderella table skirt using rhinestone brooches
