One of things that fascinates me are reports of Sasquatch, Bigfoot, Yowie, Yarin or whatever it is called in the country where you live.

Much is made of footprints left in mud or foliage and great care is often taken to get plaster casts of any prints found. These prints are often in the region 16 to 18 inches in length. Reports of stride lengths, the length from a left footprint to a right footprint or vice versa, often quote figures in the region of five feet.

I always wondered how tall a creature would have to be to have a stride length that big.

After searching the net I found this article from Scientific American on what they referred to as ‘stepping science’. For human physiology, they recommend taking the stride length then dividing it by 0.43.

Where:

• H is height
• S_t is length of stride
• 0.43 is the constant for human physiology.

Of course this constant has been set for humans and is only an approximation.

However if we choose to apply this to a five foot stride length, then we get:

That’s one tall creature.
