Toilet Roll Core Sizes Explained: 60mm, 76mm & 90mm

One of the most common mistakes when buying commercial toilet rolls is ordering the wrong core size. The core is the cardboard tube in the centre of the roll, and it has to match your dispenser. Here's a simple guide.

What is the core size?

The core size is the diameter of the central tube. For jumbo and mini jumbo rolls, the three common sizes are 60mm, 76mm and 90mm. Your dispenser is built for a specific core, so this is the first thing to check.

The three common core sizes

  • 60mm core: Common on many mini jumbo and jumbo dispensers — a widely used standard.
  • 76mm core: A very common commercial size, found on lots of jumbo dispensers.
  • 90mm core: Used on some larger jumbo dispensers.

How to find your core size

Check inside your current roll or dispenser, or measure the diameter of the cardboard tube. If you're replacing rolls you already use, simply match the existing core. If you're fitting out a new washroom, pick your dispenser first, then buy rolls to match.

Still deciding on roll size?

Once you know your core, choose between jumbo and mini jumbo based on how busy the washroom is — see jumbo vs mini jumbo. Then browse the right core size in our jumbo and mini jumbo collections.
