Indoor size vs how big it gets in the wild

Indoors and in a pot, expect around 5-8 cm tall and 8-12 cm across, spreading wider as it clusters.. A pot, your light levels and a little pruning are what set the final size in a home, far more than the plant's theoretical potential.

It grows mostly by adding leaves, offsets or a slightly wider rosette rather than gaining height — the footprint barely changes year to year.

Growth rate and years to mature

Haworthia cooperi var. truncata is a slow grower. Realistically, expect many years — it gains very little each season, so it can hold the same shelf-sized footprint for 5-10+ years. Its feeding profile backs this up: feed sparingly, about every 4-6 weeks in spring and summer, with a cactus fertiliser at quarter to half strength. do not feed in winter. these slow growers need very little, and over-feeding causes soft, distorted growth.
