Is the front flat and back flat of cardigan the same size?

The front flat of cardigan is as big as the back flat.

Cardigan sweater has the same front and back slices, and the number of stitches in the front and back slices is the same. The front piece is divided into two parts, and the back piece is one part.

Next, start knitting the back piece first. At the beginning of the back knitting, when the left and right underarms were knitted to the front, 1 needle was collected.

Then knit the back needle to the front, and then take a needle under each arm on both sides. 2 stitches under the left and right armpits.
