About this calculator
Choose a shape and desired drop to calculate the cloth dimensions. The size label rounds the required dimensions up to an even inch as a shopping reference; it does not represent a guaranteed stock size. Drop-style names are rough categories.

Disclaimer
These calculators give general estimates. Sizing, pricing, availability and standards vary by brand, retailer and country, so treat the output as a starting point and confirm it against the seller's or authority's own figures.
Implementation source
This record describes the implementation used by this page. It is not independent validation. External references, when available, support only the stated formula or definition; estimates and custom rules retain their own assumptions.
Formula and variables
C = T + 2D
- T
- Table length or diameter (in)
- D
- Drop on each side (in)
- C
- Cloth length or diameter (in)
Required cloth dimension = corresponding table dimension + 2 × desired drop. The size label rounds each required dimension up to an even inch; drop-style thresholds (<8, <15, <26 inches) are rough labels, not a universal standard.
Frequently asked questions
What does the rounded cloth size mean?
The calculator adds the desired drop to both sides of the table dimensions, then rounds each required dimension up to an even inch for the size label. It does not check retailer stock sizes. The drop-style labels are rough categories, not a universal standard.
