How to test grip strength at home

The short answer

Use a hand dynamometer if you want a number in kilograms: sit upright, elbow at your side bent to 90°, squeeze as hard as you can for about three seconds, rest, and repeat two or three times per hand. Record the best reading for each hand.

No dynamometer? Use a proxy test instead: a max-duration dead hang, the heaviest gripper you can close cleanly, or a timed pinch hold. A proxy doesn't tell you kilograms, but repeated under identical conditions it tells you the thing you actually care about — whether you're getting stronger.

Option 1: the dynamometer test

A hand dynamometer is the tool clinicians and researchers use, and basic digital models are inexpensive. The widely used protocol looks like this:

1. Sit upright in a chair without armrests, feet flat.
2. Hold the device at your side, upper arm against your torso, elbow bent at 90°, wrist neutral (not flexed or extended).
3. Squeeze maximally for ~3 seconds. Build to full effort fast, no jerking, and don't swing your arm or lean into it.
4. Rest 30–60 seconds, then repeat. Take 2–3 attempts per hand.
5. Record each hand separately — best attempt, or the average if you prefer a steadier metric. Just pick one convention and keep it.

Option 2: proxy tests with no dynamometer

Max dead hang

Hang from a pull-up bar with both hands, shoulders engaged, and time it. When your hands open, the test ends. This measures support-grip endurance rather than peak crush force, but it's brutally honest and needs zero special equipment. For a per-hand version, use assisted one-arm hangs. Full protocol in our dead hang guide.

Rated gripper close

Torsion grippers come with resistance ratings (for example 46 lb, 76 lb and up). The heaviest gripper you can close — handles touching, no body english — is a repeatable maximal-strength test. Test each hand. If you train grippers anyway, this doubles as your training benchmark; see the gripper routine guide.

Timed pinch hold

Pinch a smooth weight plate (or two thin plates pressed together) between your thumb and fingers and time the hold. This isolates thumb strength, which bar hangs and grippers barely touch.

Keeping results comparable

The single biggest error in home testing isn't the equipment — it's inconsistency. Whatever test you pick:

• Same test, same setup, same convention. Same chair, same bar, same gripper, same rest times.
• Test fresh. Grip fatigues quickly and recovers slowly; a test after deadlifts or a climbing session will lie to you.
• Both hands, always. Left–right differences of 5–10% are common; bigger gaps are worth training against, and after an injury the gap itself is the progress metric.
• Retest every 2–4 weeks. Frequent enough to see the trend, rare enough not to eat training days.

Wondering what your numbers mean? Compare against published reference ranges in average grip strength by age.

Testing during rehab

Grip measurement is standard practice in hand and wrist rehabilitation because it's objective and sensitive to change. If you're returning from injury, your physiotherapist's protocol takes priority over anything here — but consistent home measurements between appointments give both of you better data. Track each hand separately and watch the injured side close the gap on the healthy one, rather than chasing an absolute number.

Common mistakes

• Testing at different times of day or fatigue states — readings drift with fatigue; standardize it.
• Changing position between tests — elbow angle changes the number.
• Only testing the dominant hand — you lose the symmetry signal, which is often the most useful part.
• Testing weekly and panicking over noise — day-to-day variation is normal; judge the monthly trend.
• Treating one proxy as another — a longer dead hang is endurance progress, not the same thing as a harder gripper close. Track them separately.

Tracking your grip tests in MrGripper

MrGripper has a dedicated grip-test flow built for exactly this workflow — no proprietary hardware, works with any dynamometer or proxy test:

1. Open the Dynamometer tab and choose left, right, or both hands.
2. Enter your readings. The app stores each hand separately and computes a symmetry score so imbalances are visible at a glance.
3. Proxy tests (max hangs, gripper closes, pinch holds) get logged as exercises with reps or hold time — the built-in timer handles duration tests.
4. Insights show the trend over weeks, per hand, in kg or lbs — so a retest every few weeks turns into a progress line, not a note lost in your phone.
