My measurements have got all jumbled up!
Move the entries in the table to the correct place until all the measurements match up sensibly. For some items there are a few numbers which might be valid. You have to juggle them to find a combination where every measurement is valid.
This page will be different every time you load it or refresh it - so if you have unscrambled one set of measurements, you can try a new set.
The following sets of cards are available if you want to work away from the computer.
