How to Choose the Right Size Tablecloth for a 70 Inch Round Table? | Drop Rules

For the full breakdown, see our best 70 Inch Round Tablecloth guide.

Choosing a tablecloth for a 70-inch round table comes down to one calculation: add twice your desired drop to the table’s 70-inch diameter. The drop is the fabric hanging over the edge, and it must be counted on both sides. Most store-bought cloths come in standard sizes, so the formula gets you close, then you pick the nearest standard that gives you the look you want.

The Formula: Measure Twice, Add the Drop Twice

The reliable method is to measure the table’s diameter, then add twice the drop length you want. For a 70-inch table, that means a 12-inch drop needs a 94-inch cloth, a 15-inch drop needs a 100-inch cloth, and an 18-inch drop needs a 106-inch cloth.

Since standard sizes rarely match the formula exactly, buy the closest standard that is larger than your number — a slightly longer drop beats a cloth that falls short of the table.

Drop Lengths and the Standard Sizes That Match

Your drop length sets the formality. An 8-inch drop reads casual, 15 inches reads formal, and 30 inches reads floor-length, per sizing guides from Living Spaces and LoveToKnow. For a 70-inch round table, here is how the drops line up with what you can actually buy:

Either works; the difference is barely visible.

Mistakes That Leave You With the Wrong Cloth

The most common error is buying by seating capacity instead of measuring the diameter. A “70-inch tablecloth” is not made for a 70-inch table.

Another frequent miss is forgetting the drop applies on both sides. Adding a 15-inch drop to one side only gives you a 15-inch total; the correct math adds 30 inches to the table’s diameter. Measure the table’s true diameter first — across the center, not along the edge — then do the addition once, correctly.

FAQs

What is the best drop for a formal dinner?

A 15-inch drop is the standard for formal dining, which means a 100-inch cloth on a 70-inch table. If you want a slightly more dramatic look without full floor-length, an 18-inch drop on a 108-inch cloth works well and is easier to find in stores.

Should I size up if I’m between standard sizes?

Yes. Choose the next larger standard size so the cloth fully covers the table. A cloth that is too small looks accidental; one that is a few inches longer just reads as a deeper drop. For a 70-inch table, that means a 108-inch cloth over a 100-inch when in doubt.

Can I use a square cloth on a round table?

You can, but the corners will hang unevenly, with some points much longer than others. For a clean, even look on a round table, use a round cloth. If you prefer the square look, expect the drop to vary by several inches at the corners.
