A typical supermarket punnet of blueberries contains roughly 50–90 calories , depending on its size.

What a “punnet” usually means

  • Most UK/Australian punnets are around 125 g–150 g.
  • Larger family packs can be 200–250 g , but those are usually labelled by weight rather than just “punnet”.

Calories by common punnet sizes

Using typical values of about 45–60 kcal per 100 g of blueberries , here is an approximate breakdown.

  • 125 g punnet
    • About 55–75 calories
    • Based on ~45–60 kcal per 100 g scaled to 125 g.
  • 150 g punnet
    • About 70–90 calories
    • Again using the same per‑100 g range.
  • 250 g tray (sometimes called a large punnet)
    • About 110–150 calories.

Why numbers differ a bit

  • Different brands list between 39–60 kcal per 100 g / ½ cup , due to variety and growing conditions.
  • Labels from big supermarkets (like Tesco) are usually rounded for simplicity.

Quick rule of thumb

  • Treat a small punnet (125–150 g) as roughly one 60–80 kcal snack.
  • Even a larger tray is still relatively low in calories and high in fiber and vitamins.

TL;DR: For “how many calories in a punnet of blueberries”, expect roughly 60–80 kcal for a standard small punnet, and up to about 150 kcal for a big 250 g pack.
