Hello,
The joint widths generally result from the difference between the nominal dimensions and the manufacturer's dimensions or are given as recommendations by laying standards. The following applies as recommendation:
Edge lengths up to 100 mm: approximately 2 mm
from 100 - 200 mm: approximately 3 mm
from 200 - 600 mm: approximately 4 mm
Before a dispute arises between the layperson and the experts, have the statements of the parties involved explained based on SIA Standard 248 ("General conditions for tile work – coverings and claddings with ceramics, glass, and asphalt") or one of the leaflets of the Swiss Tile Association "SPV".
If the architect, for example, thinks everything is not so bad, he should be able to prove it: "What about the permissible tolerances?"
The tile supplier should also be able to professionally substantiate his opinion that the delivered tiles can be laid with a 2 mm joint (e.g., SIA 248): "To which standard or recommendation does the supplier refer?"
Of interest in SIA 248 would be the sections from Chapter 5 Execution, 5.2 Laying and 5.3 Tolerances of tile work.
