 They should be =21 x 14.8 cm= and not =210 x 148 cm=. *I have updated the dimensions
 on the live site.* I did not notice it until I saw the chart. Basically, the
 decimal point is was shifted one place to the right.

+There is a lot of duplicated sizes in these columns. The chart *had* loads of dots
+resting on top of each other so you only see five at any one point. I've removed
+all the rows with missing values and the duplicates to help show how thirty-four
+(2D) digital images only show-up as five images in the chart.
