divide into thirds

[fi-ori]

Hi everyone

I'm looking for a simple method to divide into thirds the long side of an A4 sheet of paper.
Any hints?

Thanks in advance

The simplest style would be just estimating.
Make the paper into an "S" shape and fold the edges into place. Should be quite easy.

How you divide a square into 3rds, works fine with A4 paper too.
There are some links:

Though i use to do it like folding it in half, and one diagonal, and matching the paper's vertex with one of the half's vertex, it should cross the diagonal, there will be the 3rd

Hope that helps.

Thanks everybody!

I think I'll use the S shape

@Diopside: this is your method?
