Diameter and height of 2.5 litre paint tins in UK

Good question. In the UK, tins of paint come in a standard set of metric sizes. 

Here’s roughly how diameter corresponds to size — and what you’d see that’s close to 6 inches (≈ 152 mm):

A 2.5 litre paint tin typically has a diameter of around 155 mm. 

A 1 litre tin is smaller — about 115 mm in diameter. 

So if you want a paint-tin whose diameter is ~6 inches (≈ 152–155 mm), the common UK size that matches is a 2.5 litre tin.

The height of a typical 2.5 litre paint tin in the UK depends a bit on the manufacturer and shape (round, rectangular, lever-lid, etc.), but common values are:

• Many round 2.5 L tins have a height of around 157 mm.
• Some variants list about 155 mm.

So you can estimate ~15.5–15.7 cm tall for a standard 2.5 L paint tin.
