You are watching: Half of 9 3/4 inches

In the video clip above, Tom Silva demonstrates the 2 methods. The first is easier since it entails only one ice measure:

Measure your item. In this case, a board.Round as much as a bigger number that’s conveniently divisible by two. In this example, 40 inches.Pull a tape measure up diagonally across the board until the 40-inch graduation aligns v one edge.Make a pencil line at the 20-inch graduation heat (half that 40). That’ll be the facility of the 37 5/8 inch board.

The second technique is come use 2 tape measures, pulling each across from opposite edges, and find whereby the identical measurement is. That’s the center.

Math is fun, but sometimes mathematics shortcuts are even an ext fun.

Is it simply me, or carry out both of these seem too many complicated? can not you just fold the tape measure in half? that’s even simpler with tailor’s tape.

Or I’ve also used twine; traction twine alongside the ice cream measure, cut it the very same length and just wrinkles that in half ...

As one aside, transferring twine is much easier than carrying a tape measure also. One point that twine can do because that you it is cool, if you are looking at a bunch of the very same items to check out if one will certainly fit, prefer whether girlfriend can obtain a bed with your apartment door (or come fit in her room), cut a couple of pieces the length and also width the the area you’re concerned about, role ‘em up in your purse, coat pocket, wherever, and also take off. Currently when you’re out trying to find beds yes sir no must remember room size or lug a tape measure up everywhere, simply stretch the twine the end on the floor through the item and et voila, you’re done.

I must make mine own show “This Old Man” v a bunch of tricks that space useful, but additionally absolutely guarantee to awkward the kids ;)
