Most blueberry bushes grow anywhere from about 1 foot to around 10–12 feet tall at maturity, depending heavily on the type (and pruning).

Quick Scoop

  • Lowbush blueberries: about 6 inches to 1–2 feet tall, often used as groundcover.
  • Highbush blueberries: usually around 5–9 feet tall when mature.
  • Half-high (hybrid) blueberries: roughly 3–4 (up to 6) feet tall.
  • Rabbiteye blueberries: some of the biggest, often 6–10 feet tall and similar in width.
  • Overall range: most home-garden blueberry bushes end up between 1 and 12 feet tall and wide, with many common varieties sitting in the 4–8 foot range if not heavily pruned.

How width compares

  • A mature blueberry bush is often about as wide as it is tall when grown in good conditions.
  • Larger types like Rabbiteye can easily reach 6–10 feet wide if you let them grow naturally.

What affects how big they get

  • Variety (lowbush vs highbush vs Rabbiteye is the main size driver).
  • Climate and soil (acidic, well-drained soil and full sun push them toward their maximum size).
  • Pruning (regular pruning keeps even large varieties more compact, but you can let them grow into big hedge-like shrubs).

Think of lowbush blueberries like a little berry carpet, highbush like a person-sized shrub, and Rabbiteye like a small, fruiting tree you could almost hide behind.

TL;DR: For planning space, assume most full-size blueberry bushes will need about 4–8 feet of height and similar width, unless you specifically choose dwarf/lowbush types or keep them smaller with pruning.
