Average Grip Strength by Age and Sex (kg Chart)

19 July 2026 · 7 min read

"Is my grip strength normal?" is one of the most common questions people ask once they measure it for the first time. The honest answer: it depends heavily on your age and sex — and it varies more than most people expect. Here's a reference chart, what drives the numbers, and how to find where you rank.

How is grip strength measured?

Before any number means anything, you need to know how it was produced. The standard tool is a hand dynamometer — a device you squeeze as hard as you can while it records the peak force. Most research and clinical norms report that peak in kilograms (kg) or, sometimes, pounds.

The widely used protocol from the American Society of Hand Therapists is specific on purpose: sit upright, shoulder relaxed and adducted, elbow bent at 90 degrees, forearm and wrist neutral. You squeeze for a few seconds, rest, and repeat — usually three times per hand — and take the best or the average of those trials. The point of all that fuss is repeatability. Change your posture, your elbow angle, or which grip-width setting you use, and the number moves.

Two practical consequences follow. First, most norms are reported for the dominant hand, so compare like with like. Second, consistency beats precision: testing the same way each time tells you far more about your own trend than chasing the "true" number on a lab-grade device.

How does grip strength change with age?

Grip strength follows a fairly predictable arc. It climbs through your teens and twenties, peaks in your early-to-mid thirties, holds through midlife, then declines — slowly at first, then faster. As a rough guide, median dominant-hand grip peaks around 50 kg for men and 30 kg for women.

After roughly age 50 the decline is commonly cited at about 1–2% per year, and it accelerates past 70. One analysis of European older adults illustrates the shape: men lost around 3.5 kg per decade between 50 and 60, rising to about 6.5 kg per decade between 70 and 80; women lost roughly 2.3 kg then 4.1 kg over the same decades (PMC9518361). The drop isn't fixed, though — it tracks how much strength and muscle you keep, which is why staying active matters.

Average grip strength by age and sex

These are approximate reference values for handgrip strength (dominant hand, in kilograms). Grip varies with body size, hand dominance, and how it's measured, so treat them as ballpark medians, not pass/fail lines.

Age	Men (kg)	Women (kg)
20–29	~47	~29
30–39	~50	~30
40–49	~47	~29
50–59	~42	~26
60–69	~37	~23
70–79	~31	~20
80+	~25	~16

Want the full percentile breakdown for your group? Each of these has its own reference page:

Men aged 30–39 · Men aged 40–49 · Men aged 50–59
Women aged 30–39 · Women aged 40–49 · Women aged 50–59

What does a percentile mean?

A median is the middle of the pack. A percentile tells you how you stack up against everyone else in your age and sex group. If you're at the 50th percentile, half of people your age and sex score below you and half above. At the 75th percentile, three-quarters score lower. At the 10th, only one in ten score lower.

That framing matters because a single median hides a lot of spread. Two people the same age can differ by 15 kg and both be perfectly healthy. So when you open a reference page, read your number as a position in a distribution, not a grade. Below the median simply means "there's room" — not "something is wrong."

Dominant vs non-dominant hand

Your dominant hand is usually a little stronger, and the old rule of thumb is about 10%. The real picture is looser. A meta-analysis of upper-limb asymmetry found the dominant limb averaged about 11.6% stronger across the whole upper limb, though for grip specifically the gap was smaller — roughly 8% (Nature Scientific Reports, 2025). And the classic "10% rule" has been challenged for decades: one study found it held for right-handers but not left-handers, whose two hands were essentially equal (AJOT, 1989).

Practical takeaway: expect your two hands to differ by roughly 5–15%, don't panic if it's more or the "wrong" way around, and always compare against norms using the same hand the norms were built on.

What drives individual variation?

Hand dominance. Which hand you tested, per above.
Body size. Bigger hands and more muscle mass generally mean higher raw numbers. Grip scales with overall build.
How it's measured. Dynamometer model, grip-width setting, posture, and effort all shift results — consistency matters more than the exact device.
Time of day and fatigue. Test rested, the same way each time.
Training history. Grip responds to loading like any other trait. People who lift, climb, or work with their hands tend to sit higher.

None of these are pass/fail. They're reasons two honest, healthy people can land far apart on the same chart.

How do I find where I rank?

Measure your grip the same way each time.
Compare against the table above (or your specific reference page).
If you're below the median for your group, that's simply a starting point — grip responds well to training at any age.

Griply turns each test into one honest 0–100 Grip Score and charts it over time, so "am I normal?" quietly becomes "am I improving?" — the more useful question. Measure, train five focused minutes a day, re-test.

When is a low number worth discussing with a professional?

Grip strength is a well-studied proxy for overall muscle health, which is why it's worth paying attention to — but a single low reading is not a diagnosis. In older adults, clinicians use it as a screening signal: the European Working Group on Sarcopenia in Older People (EWGSOP2) flags grip below roughly 27 kg for men and 16 kg for women as a prompt for further assessment, not as a verdict (PMC8037004).

Consider talking to a doctor or physical therapist if your grip is well below the norms for your age and sex, if it has dropped noticeably over months without an obvious cause, if one hand is much weaker than the other, or if weakness comes with pain, numbness, or trouble with everyday tasks. For most people, a below-average number is a training opportunity — not a medical event.

Frequently asked questions

What is a good grip strength?

A reasonable target is at or above the median for your age and sex — roughly 50 kg for men and 30 kg in the dominant hand for adults in their thirties, sliding down from there with age. "Good" is relative to your group, and above the median is a fair goal. Because your own trend is more useful than any single benchmark, aim to hold or improve your number over time rather than hit one fixed figure.

Is grip strength genetic?

Partly. Body size, frame, and baseline muscularity have a heritable component, so some of where you start is out of your hands. But grip is highly trainable — the day-to-day and year-to-year differences between people owe a lot to activity, occupation, and training. Genetics set a range; what you do decides where in that range you land.

Why does grip strength peak in your 30s?

Muscle mass and neuromuscular efficiency generally reach their high point in early adulthood. Grip strength tracks that, cresting in the early-to-mid thirties before the gradual, then steeper, age-related decline sets in.
