What does this number measure?
A regulation length of 2.74 metres. The table tennis table is divided by a net. The reference compares its total length, not the height of the tabletop or the net.
Compare the stated dimensions
The comparison uses the number in each fact sheet: altitude, height, diameter, length or distance, depending on the reference. Two values in metres do not necessarily describe the same property.
Source and limitations
Catalogue order of magnitude; a source is provided, but this measurement has not been individually audited.
Complete table tennis table, horizontal length.
Model not specified: Varies by period. Proposed historical date; an existing documentary source is linked but was not consulted for this date in this session. Do not interpret this reference as the manufacturing date of the illustrated specimen. Generic regulation table; no particular installation or manufacturing date is identified. A universal year would be misleading.
