Fitting and Sizing Guidelines

Proper fit is the correct combination of width and height. As a thimble gets wider, it also becomes higher.

1. The thimble is fitted to the tip of the middle finger on the hand with which you sew or write. If it is too close to the first joint, it will interfere with the normal range of motion.

2. The thimble should be snug but comfortable. The thimble should not fall off when the hand is shaken upside down.

3. If it is too tight, it will cause the finger to perspire and throb. If it is too loose, it will be difficult to keep on while sewing. In a properly fitted thimble, you should be unaware of its presence.

To Determine Correct Size:


  1. Carefully measure (in mm) the inside diameter of an existing thimble you now use and consider comfortable. Do not include the thickness of the thimble. You should get a measurement between 13-19 mm. This measurement can be converted to a size in all of our thimbles
  2. If you do not have a thimble that fits, go to your local fabric shop and try on the Dritz brand as these come in several sizes. Make note of the size so we can convert this to one of our thimbles.




  1. Cut a piece of aluminum foil about 6″ long and about 1″ wide. Fold it lengthwise twice so that it measures about 1/4-3/8″ in width.
  2. Wrap the foil snugly around your thimble finger beginning at the cuticle edge. Twist the ends of the foil to secure and slide the foil ring off your finger.
  3. Make the ring as round as possible. Measure the diameter of the ring (in mm). We can convert this measurement to a size in one of our thimbles.

Please note:
There is no consistency in sizes among thimble manufacturers.
