Choosing the wrong tablecloth size is one of the most common mistakes at South African events โ either the cloth is too short and exposes the table legs, or it's too long and bunches on the floor creating a trip hazard. This guide gives you the exact formula to get it right every time.
The Universal Formula
The formula for calculating tablecloth size is straightforward:
Cloth size = Table diameter/length + (2 ร desired drop)
The "drop" is how far the tablecloth hangs below the table edge. Standard South African event tables are 75cm high.
- Floor-length drop: Drop = 75cm (cloth touches the floor)
- Lap-length drop: Drop = 30cm (cloth hangs approximately to lap height)
- Standard event drop: Drop = 45cm (most common for South African events)
Round Table Calculations
For a round table, the formula is: Cloth diameter = Table diameter + (2 ร drop)
- 120cm table (seats 4โ6), floor-length: 120 + (2ร75) = 270cm โ use 300cm cloth
- 150cm table (seats 8โ10), floor-length: 150 + (2ร75) = 300cm โ use 300cm cloth โ
- 150cm table (seats 8โ10), lap-length: 150 + (2ร30) = 210cm โ use 230cm cloth
- 180cm table (seats 10โ12), floor-length: 180 + (2ร75) = 330cm โ use 330cm cloth
The 150cm round table with a 300cm cloth is by far the most common combination at South African events โ it's the standard banquet setup for weddings, church functions, and corporate galas.
Rectangular Table Calculations
For a rectangular table, calculate both dimensions separately:
Cloth length = Table length + (2 ร drop)
Cloth width = Table width + (2 ร drop)
- Standard 6ft trestle (183ร76cm), floor-length: Length: 183+(2ร75)=333cm โ 305cm cloth. Width: 76+(2ร75)=226cm โ 152cm cloth. Use 152ร305cm cloth.
- Standard 6ft trestle (183ร76cm), lap-length: Length: 183+(2ร30)=243cm โ 274cm cloth. Width: 76+(2ร30)=136cm โ 152cm cloth. Use 152ร274cm cloth.
Trestle Table Cover (Fitted)
Fitted trestle covers are a different product from rectangular tablecloths โ they are sewn to fit snugly over the table with a fitted bottom, like a bed sheet. They look far neater than draped rectangular cloths and don't slip.
- 1.8m trestle table: Use a fitted 1.8m trestle cover
- 2.4m trestle table: Use a fitted 2.4m trestle cover

Common Mistakes to Avoid
- Measuring the table top only: Always measure the full diameter including the table edge, not just the usable surface area
- Forgetting the drop: A 150cm table needs a 300cm cloth for floor-length โ not a 150cm cloth
- Ordering too small: A cloth that's too short looks worse than one that's slightly too long
- Not accounting for different table heights: Bar-height tables (110cm) need a larger cloth than standard-height tables (75cm) for the same floor-length drop
