HOW TO SIZE GOALKEEPER GLOVES — GUIDE 2025

90% of glove returns in Poland are due to wrong size. Not because customers don't know how — because nobody explained it to them. Football Masters, a Polish brand since 2014, has conducted over 200,000 measurements. This guide is the essence of that.

The most common question we get: "I'm 185 cm tall, what size?". Answer: irrelevant. Glove size is a function of palm length and width, not height, weight, age, or position. Know your hands — know your size.

This guide shows you: (1) how to measure your hand correctly in 60 seconds, (2) how to read the FM size chart (6–11), (3) when to intentionally go up or down a size, (4) three most common measurement mistakes.

1. How to Measure Your Hand — 60-Second Method

You need: tailor's tape (or string + ruler), paper, pen. That's it.

  1. Measurement A — hand circumference. Wrap the tape around the widest part of your hand (just below the knuckles, excluding thumb). Hand relaxed, fingers together. Record the result in centimeters.
  2. Measurement B — hand length. Lay your hand flat on paper, fingers naturally spread. Measure from the wrist base (bracelet line) to the tip of your middle finger.
  3. Key measurement = measurement A (circumference). That's what determines size. Length serves as a verification check.
Practical tip: measure your glove hand — the one you catch with. A 3–5mm difference between left and right is normal, but choose the size of your larger hand.

FM sizing matches the German latex factory standard we've worked with since 2014 (Reusch, Uhlsport, Rinat use the same chart). If you wear size 9 at another brand, you wear 9 with us—sizing transfers.

3. When to size down (tight fit)

A "fitted" goalkeeper size is one where your fingers reach the end of the glove with loose 5-8 mm. Some prefer snug. Go down 1 size if:

Warning: a tighter size means faster latex wear (material tension) and reduced thermoregulation comfort. If you play 3× per week, stick with standard sizing.

4. When to size up (comfort fit)

5. Three most common measurement mistakes

Mistake #1 — measuring with your thumb. The thumb adds 2-3 cm to the circumference, which translates to 1-1.5 sizes too large. The thumb MUST be excluded from the measurement.

Mistake #2 — tensing your hand. A tense hand is about 1 cm smaller in circumference than a relaxed one. Measure in neutral position, the way you catch the ball.

Mistake #3 — measuring over clothing. Cuffs, sleeves, wristbands — they all skew the measurement. Bare hand, clean measure.

6. What to do if your measurement falls between sizes

FM rule: for kids always choose larger (grow quickly, 6-month range). For adults — smaller, because the glove stretches slightly after 2-3 training sessions (latex warms up, fabric gives 1-2 mm).

Exception: Invictus X Pro with Negative cut — Negative generally fits tighter than Roll Finger, so at borderline measurements, go up higher size in Negative, lower in Roll Finger. Details — see our guide to cuts.

7. What the source says — FIFA Equipment Regulations

FIFA Equipment Regulations don't specify exact glove size, but require that the glove must "fit the hand comfortably and securely, without risk of slipping during play." In practice: not loose. Full regulations at FIFA Equipment Regulations 2023 (PDF).

Summary in 3 points

  1. Measure your palm circumference (without thumb, relaxed) — this is the only number that determines size.
  2. FM table = German standard — if you get a 10 from another brand, you get a 10 from us.
  3. Boundary → seniors down, kids up. Negative cut fits tighter, Roll Finger looser.

Size isn't a detail. A glove one size too big means 20% slower reaction — extra finger room delays the moment your hand closes on the ball. One size too small and you're exhausted after 30 minutes. Choose wisely, once, right.
