what is the center back measurement on the hexi caridgan

The center-back measurement for a hexi cardigan is usually taken from the exact center of the hexagon to the midpoint of one outer edge, and that half- width is then doubled to estimate the full back width or multiplied by 4 to estimate chest circumference. One crochet guide specifically says to “measure your hexagon from the center to the edge, and multiply by 4,” while another explanation says the center-to-edge distance represents about a quarter of the full chest measurement.

How to use it

• Measure from the center of the hexagon to the middle of one side.
• That gives you the key sizing number for the back panel.
• If you want a chest estimate, multiply that number by 4.
• Compare the result to your desired bust circumference plus ease.

Simple example

If your center-to-edge measurement is 10 inches, the approximate chest measurement is 40 inches. That is the number you’d use to check whether the cardigan will fit comfortably.

Note on wording

People sometimes say “center back measurement” when they really mean the center-to-edge size of the hexi piece, not a traditional garment back length. A forum post also describes a finished cardigan measured from center back neck to center bottom as a separate length measurement, so it helps to confirm which dimension you mean.
