Where does the phrase 'Fits to a T' come from?

Question

And what does the T stand for?

Answer 1

I would guess it is referring to a T-square or tool used to make sure floors and roofs are level. A carpenter or handyman or someone in construction or even furniture or cabinetry making might be able to confirm this for you.
Another possibility is that it is referring to drafting. See link below.

Answer 2

: : If something "fits to a T" then it's perfect for its purpose. The allusion here is said to be with a T square. This piece of apparatus is so accurate that a precise right angle fits it perfectly.

: : However neat this suggestion is, there is another possible origin, based on the fact that the saying was in use in the 17th century, before the T square was invented. This one suggests that the T stands for "Title", a minute and precisely positioned pen stroke or printer's mark. A tiny brushstroke was all that distinguished the Hebrew letter "dalet" from "resh". "Title" was the word chosen by Wycliffe to translate references to this tiny difference in his version of the New Testament. Thus the mark was perfectly suited to its task.

Answer 3

i think that it comes from the taylors back in the day and instead of saying it fits like its taylor made they say it fits to a t. I dunno but it sounds good to me.

Answer 4

Maybe because we are "T" shaped?

Sholders are the top and the rest of it is our body?

just guessing here
