.
It needs 1 meter * sin(8°) lateral space in each direction.

A 1 metre pendulum swings through an angle of 8 degrees. How much lateral space (side to side space) does it need to swing?
------------
It swings 4 degs to each side.
--> 2sin(4) meters
===============
The other tutor's answer was close.
2sin(4)/sin(8) =~ 0.99756
------------------
Pendulums used for timing, as in clocks, usually limit the swing to 8 degs.
The characteristics are not clearly defined for larger angles.
For angles <= 8 degs, the sine is "nearly the same" as the tangent.
