Subject: Measuring the curling stones

Question:
I would like an explanation on the proper use of the measuring stick. Thank you.

Answer:
Thank you!

Your question is greatly appreciated and always welcomed.

There is a whole section of the rule book and part of the officiating course that is devoted to measure within the curling rings.

14. Measuring
(1) Measurements shall be taken from the tee to the closest part of the stone.
Interpretation: Because stones may vary in diameter, measurements shall not be
taken from the tee to the farthest part of a stone.
(2) No physical device to aid visual observation shall be used in measuring prior to
the last stone delivered in the end coming to rest except as provided for in Rule
12(2).
(3) Decisions on whether a stone is in or out of play shall be visual (no accepted
measuring device). If the opposing teams cannot agree, they may request a
non-partisan third party to render a decision.
(4) If two or more stones are so close to the tee that a measuring device cannot be
used, and if a visual comparison cannot determine which stone is closest to the
tee, the stones shall be considered tied. If these stones were to determine who
counted in the end, the end shall be considered blank.
(5) A measuring stick that measures a distance of six feet from the tee shall be used,
if necessary, to confirm whether a stone is within six feet of the tee as provided
for in Rule 12(2) and 13(5).
