Count System for size 1 Is the number of yards required to make 1 pound of size 1 cotton, linen or wool.

840
Linen, hemp, jute, ramie

Size 2 indicates there is twice the yardage and half the diameter of size 2
Such as 2 x 840 = 1680 yards per pound
When two strands of a single or 1 ply are twisted together, it is known as a 2 ply. 4 strands as 4 ply, etc.
Another method to determine sett - Wind the warp yarn around a ruler for one inch. Wind the yarn firmly, evenly without stretching the yarn. Don't let the yarn overlap and don't leave spaces. Count the number of wraps in an inch.
NOTE: If mixing yarns in a warp, wrap ruler with each yarn.
To determine ends per dent in a chosen reed Find reed size at top, follow the column down to your EPI, cross to find the order of sley in the far right column.
