Field notes
Buy 10% over for a straight grid and 15% for diagonal or herringbone — the angled cuts at the perimeter are pure waste, and you want a few spares from the same lot for future repairs. Dry-lay a row before you spread thinset to find your layout and avoid a sliver-width cut against the most visible wall. Order all your tile in one lot; shade varies between production runs.
