Arrow shafts

I was looking to get new arrows soon so i went online and it said arrow shaft with a number like 340. I looked at my arrows and they are 300 what does this number mean

It's the spine. The box should have a chart telling you which arrow to shoot based on how fast you bow shoots, length of arrow, grains, etc. when I got my arrows cut shorter, I needed more spine so I went from 340s to 400s.

The higher the number, the more flex (spine) the shaft has.
