There is a formula for figuring out how bed space is allocated. It is called the “Foot Rule”. You start by determining the total number of feet (as in those at the end of the legs, not the kind made up by inches). Then you divide that total by the number of feet belonging to the person(s) or cat(s) in question.
This is how it works:
You and husband share your bed with 1 cat. You and your spouse total 4 feet and the cat also has 4 feet. That is a total of 8 feet. The cat has 4 out of 8 feet or 50%, therefore, the cat gets 50% of the bed.
You could work this in reverse as well. You have 2 out of 8 feet or 25% and so does your spouse, so each of you gets 25% and the cat gets 50%.
Now I have 5 cats. At 4 feet per cat, that is 20 feet. Add to that my 2 feet and we have a total of 22 feet in the bed. I have 2 out of 22 feet which is 1/11th or 9.1% of the bed. The cats, since they share a total of 20 of 22 feet, get 10/11ths or 90.9% of the bed. Simple isn’t it?!
Once I figured out my percentage of the bed space, the next step was to work out the exact area that I am entitled to. My bed is a King size and is approximately 6 ft x 7 ft. Here is the maths:
6 ft x 7 ft = 42 square feet
42 square feet = 6048 square inches
9.1% of 6048 = 550 square inches
550 square inches = 45.8 total inches
45.8 inches = 3.8 total feet
In order to determine the exact size of my bed space, I needed to know the percentage of length to width – this comes out to 54% long to 46% wide. When I apply these percentages to my spot:
550 square inches x 54% = 297 square inches 550 square inches x 46% = 253 square inches
297 square inches = 24.7 inches
253 square inches = 21.1 inches
24.7 inches = 2.1 feet
21.1 inches = 1.8 feet
Now that the maths is done, the figures show that the dimensions of my part of the bed are 2.1 feet by 1.8 feet – or in other words I sleep on my pillow.
