Size and burn time

A larger piece contains more charcoal, so it burns longer. That's why, when you compare quality grades or suppliers, you should always compare the same size. Burn time for our products ranges from 60 minutes to 2.5 hours, depending on grade and size.

Size and pieces per box

The larger the size, the fewer pieces per kilo. For cube charcoal:

  • 25 mm72 pieces per 1 kg box
  • 26 mm64 pieces per 1 kg box
  • 27 mm56 pieces per 1 kg box

Some customers compare boxes by piece count, others by weight. Find out how your customers compare before you choose.

How do you choose the size?

  • Bowl size: large bowls need bigger pieces or more of them.
  • Session length: cafés and long sessions benefit from larger sizes.
  • Market habits: ask distributors and cafés which size their customers are used to.
  • Test first: request samples in more than one size before placing a large order.

Next step

See every shape on our products page, read about the difference between charcoal shapes, then state the size you need in your quote request.

Size and bowl type

The right size also depends on the bowls common in your market. Small and medium bowls work well with 25 or 26 mm cubes, while large bowls and heat management devices that take bigger pieces benefit from 27 mm or flat shapes such as hexagonal and dome. If your customers use heat management devices with specific openings, check the piece size that fits before ordering.

Because size changes the piece count per box (72 at 25 mm, 64 at 26 mm and 56 at 27 mm in a 1 kg box), it also changes how many sessions a customer gets from a box, which matters for pricing and marketing.
