What size of glove is right for me?

Learn how to properly size electrical rubber insulating gloves using ASTM D120 guidelines. Measure palm circumference for a safe, comfortable, and accurate glove fit.

Why Proper Glove Sizing Matters

Selecting the correct size electrical rubber insulating glove is essential for both safety and comfort. A glove that is too tight can restrict dexterity and hand movement, while a glove that is too loose may reduce control and increase fatigue during energized work. Proper sizing ensures optimal protection while maintaining the tactile feel technicians need in the field.

ASTM D120 Sizing Reference

According to ASTM D120 Section 8.2, glove sizing is based on the circumference (diameter) of the palm, measured at the midpoint of the palm (± ½ inch tolerance).

This standard provides manufacturers with consistent sizing guidance and helps users select a glove size that corresponds closely to their hand dimensions.

How to Measure Your Hand for Electrical Gloves

Step-by-Step Measurement

  1. Use a flexible tape measure.
  2. Wrap the tape around the widest part of your palm, just below the knuckles (do not include the thumb).
  3. Ensure the tape is snug but not tight.
  4. Record the measurement in inches.

Your palm circumference measurement typically equates to the glove size you should select. For example:

Palm Circumference (inches) Recommended Glove Size
8" Size 8
9" Size 9
10" Size 10
11" Size 11
12" Size 12

Example: A 10-inch palm circumference generally corresponds to a Size 10 electrical glove. Easy, right?

Comfort & Personal Preference

While ASTM sizing provides the baseline, personal preference plays an important role in final selection. Consider:

  • Tighter fit: Better tactile feel and dexterity
  • Looser fit: Easier donning/doffing and room for liners
  • Finger length: Some users may size up for longer fingers
  • Inner liners: Cotton or arc-rated liners may require sizing up

Ultimately, the best glove size is the one that provides both secure insulation coverage and all-day comfort.

Choosing the correct size electrical glove is a simple step that significantly improves protection, performance, and confidence while working on energized equipment.
