Just remember it’s:
The length of a musk ox or fully-grown llama
Three Rubik’s Cubes plus one Keir Starmer
Eleven seven-inch singles by Bananarama
That’s what two metres is.

Alternatively, it’s:
1/ 192,199,930th of a single moon beam
2.2 times greater than Munch’s The Scream
About 10½ packets of custard creams
That’ll be two metres.

If easier, think:
Thirty-three pairs of dragonfly wings
The length of a yoga mat belonging to Sting
Two one-metre long pieces of string
That comes to two metres.

Or failing that, imagine:
0.00000091 of the coast of mainland Wales
18.2648402 cricket bails
One and a quarter Prunella Scales
That’s two metres.
