How large is your king?

What do you do when you have to buy a bedsheet for a king size bed?

It's obvious: you look up what size king size is. Unfortunately, at this point the all-knowing Wikipedia offers a lot of choice:

• Is it 60" × 78" (151cm × 197cm)?
• Is it 72" × 78" (181cm × 197cm)?
• Is it 59" × 79" (149cm × 199cm)?

As do other mortals, clearly kings come in all sizes!

In the end it turns out the bed is really 135cm × 200cm, or what in Dutch we call a doubter (twijfelaar). Or maybe it isn't?
