Antique Extension Table Seating Capacity Calculator

Understanding the result

This calculator estimates places around the usable table perimeter. It accounts for length, width, shape, leaf count and comfortable width allowance per diner. Chair size, pedestal legs, corner geometry, table aprons, room clearance and guests’ needs can reduce practical capacity. Confirm with the actual chairs and table.

• These results support research and planning; they do not independently establish authenticity, age or value.
• Keep direct observations separate from assumptions, seller claims and conclusions.
• Seek qualified, object-specific advice when the decision affects value, repair, safety or a legal transaction.

Good records improve research

Keep original observations separate from conclusions. Photograph the whole object and relevant details in even light; record dimensions, labels, maker marks, repairs, provenance and the references consulted. Do not alter the object just to obtain another clue.

Methodology and limitations

For a rectangular table, estimate side places from usable side length divided by preferred space per diner, then consider end seats if the table and leg arrangement allow them. For oval or round tables, use the entered effective perimeter as a planning approximation. Always round down for a comfortable plan.

A 180 cm rectangular table with about 60 cm per diner may comfortably provide roughly three places along each long side, with possible end seats depending on leg placement and chair width.

Historical objects are often repaired, refinished, reassembled or made from more than one material. Modern reproductions may imitate older processes. A likely match should always be phrased as a research hypothesis unless it is supported by a qualified, object-specific assessment and trustworthy documentation.
