Estimating Length by Measuring Shed?

Is this an accurate way to estimate the length of your snake? (Personally) I've always felt like the sheds look a little stretched out. How far off do you guys think this measurement would be?

They seem to shrink when they dry out, so if anything I would think they'd be a little shorter than the snake.

The best way, in my opinion, to think about it is how you titled the thread: estimation. It's difficult to measure the snake itself, so a shed is as good and easy as it gets; what you get is an approximation, and you can round up or down how you please. Besides, we don't base breeding readiness on length but weight. :D

Snake sheds can stretch by more than 25%. So they are not an accurate way to measure the length of a snake.

There is the string method. Where you take a string and run it down the center of the back from the nose to tail. Then measure the string.

You can allow them to crawl along a wall and mark the head and tail. Then measure the marks.

There is also a program which allows you to take an aerial picture with and object of known size and it will figure up the length for you.
