Guestimated Measurements


Here's what I do when I don't have a tape, to figure (rough) measures:

My right hand span, thumb to middle finger, is 9" (multiples of 9, good for door widths, or anything else)
My reach up is about 7' 6" (figuring 8' high)
My arms spanning outward is my height, 6' (wall width, lumber lengths)
My outstretched arm to nose is 3' (doorways)
My right index finger is 1 1/4 inches tip to first joint. (screw/nail lengths &c.)
My foot is just about 12" (duh) (floor lengths, tiles, &c.)
My eye level is 68" (good for hanging pictures)
And I have 10 fingers (metric)

&c.
But your mileage may vary.

Any others?
(keep it clean)

Guestimated Measurements


My situation: I take precausions to not have to guess. The way I see it, is, that in my line of work, I am in need of a tape measure and the ability to make accurate measurents at all times of a work day (like a CPA needs a calculator).

So, I carry a tape measure with me (clipped to my belt - next to my cell phone PDA).... everywhere I go, on work days.
(I also keep spare tapes in the front and back of my personal work truck, and also in the backs of all our company work trucks and trailers = so they are always around).

Gee, you are getting pretty technical on this guy Atlantic, with using a tape measure for everything. . I guess you did not see his motto beneath his screen name, "do, undo, then do it right". Pretty much explains why he doesn't need a tape, only a few body parts.

We all have done some "rough" guestimates occassionally, like stepping off a room size, but I don't think I want to start using body part measuments to order a job full of door units or finger increments to select a screw from my truck where an 1 1/4" will work fine, but a 1 1/2" will put a screw point throught the side of a cabinet.

I readily admit that I am anal, particilarly with stuff I need to have, and that may break, get lost etc; tape on me , tape in glove box, two tapes in rear of truck, never less than three pencils in my shirt pocket and pack in glove box, enough jig saw blades and driver bits that I probably could go 6 mos. and not run out, etc.

Even with six or seven tape measures I still use informal systems. I write the measurements of everyday tools on them with permanent marker. Goofy, yes. Useful, yes. But, I also write myself little notes like: DON'T THROW THIS AWAY; WHERE ARE YOUR GOGGLES? CHECK FOR CURRENT BEFORE CUTTING. That sort of thing. I think it's cause my mom used to write notes to me on my lunch bag.

I had a builder friend who's moto was: Pound to fit; Paint to match. Using this moto, guestimates may be just fine.
