See Measuring Yardage for a Tablecloth for more information on this step, including diagrams. It also explains how to figure out how many yards you’ll need to buy.
First, decide what you want the drop length to be. This is the distance from the edge of the table to where you want the tablecloth to end. Drop lengths are generally about 10 to 12 inches for everyday use or they can go all the way to the floor for a more formal look.
I’m going to make a floor length tablecloth for this table. (Just be aware that the corners will pool on the floor with long tablecloths like this one.)
Measure the length and width of the table and the height if the drop will be floor length.
This table is 61” long, 30” wide, and 36.5” tall. I’ll make the drop 36” so it’s a little off the floor. Normal table height is about 30 inches.
Finally, you have to know if you need a hem and if so, what size. I’m going to do a ½” double folded hem.
Calculate the width of the tablecloth:
Table Width + (2 x Drop) + (2 x Hem) = Total tablecloth Width
For my table that’s 30” + (36” x 2) + (1” x 2) = 104”
Calculate the length of the tablecloth:
Table Length + (2 x Drop) + (2 x Hem) = Total tablecloth Width
For my table that’s 61” + (36” x 2) + (1” x 2) = 135”
If your fabric is wide enough for the tablecloth, simply cut 1 piece to the total length and width and move on to hemming in step 3.
If your tablecloth will be wider than the width of your fabric, you will need to cut more than one piece and sew them together.
This fabric is 60 inches wide and the total width is 104”, so I need to use 2 widths of fabric.
Instead of having a seam down the middle, it looks better to have a full width panel in the center with two narrower pieces on the sides.
I’m cutting two pieces of fabric to 135” in length. Cut one of the pieces in half lengthwise.
