We all tend to use comparatives to express sizes, lengths, or the heights of things that would otherwise be tricky to estimate.
Tall things tend to be compared to the height of Nelson's Column, long things to Cricket Pitches, and volumes to how many could fit inside Wembley Stadium (above).
Countries sizes are often compared to the number of Wales's that could fit into them.
Room sizes can be compared to the size of a Double Decker Bus, as can Satellites. Front Gardens are often compared to Handkerchiefs. Thickness by Planks or Bricks. Brightness by Buttons. And certain liquid quantities by how many Olympic sized swimming pools they can fill.
Width can be measured in Tennis Courts, obesity by Pigs, attractiveness by Pictures or the rear of Buses, thinness by Rakes, and the lack of hair by Coots.
The British are an inventive lot. More please!
