How many meters long is a Torah scroll?

Answer 1

Torah scrolls vary widely in physical size. The text of every Torah is hand-written

in 245 columns, of 42 lines in each column, but the height of the script and the

width of the columns varies over a wide range among scrolls.

As a frequent reader, I'll estimate for you that a typical scroll used for the public

synagogue reading may run something like 1 foot per column. That would make

the entire scroll 245-ft long, which would be in the neighborhood of 75 meters.

That should be taken only as a rough, generic guesstimate, from the ballpark.
