The short answer
The median grip strength for women aged 25–29 is 29.4 kg (64.8 lb), from the Tomkinson 2025 international norms. Low for this group is below 24.5 kg (54.0 lb), the 20th percentile on this ladder. High is 34.6 kg (76.3 lb) and above.
This page covers ages 25, 26, 27, 28, and 29.

What counts as low, average, and high at this age
The authors of the norms classify five bands. On this ladder those bands are real kilogram ranges, not slogans:
| Band | Grip at this age |
|---|---|
| low | below 24.5 kg (54.0 lb) |
| somewhat low | from 24.5 kg (54.0 lb), which is the lower edge of the band, through 27.9 kg (61.5 lb) |
| moderate | from 27.9 kg (61.5 lb), which is the lower edge of the band, through 30.9 kg (68.1 lb) |
| somewhat high | from 30.9 kg (68.1 lb), which is the lower edge of the band, through 34.6 kg (76.3 lb) |
| high | 34.6 kg (76.3 lb) and above |
How wide the spread is
The gap between the 20th and 80th percentile here is 10.1 kg (22.3 lb). Comparing yourself to a single “average” hides most of the distribution. Two healthy women in the same five-year band can differ by more than that spread without either being unusual.
How this group compares to the peak
The median here is 0.3 kg (0.7 lb, 1.0%) below the peak at ages 30–34 (29.7 kg (65.5 lb)).
What to expect over the next ten years
Ten years on, the population median for women aged 35–39 is 29.7 kg (65.5 lb) — 0.3 kg (0.7 lb) higher than this group. That is a cross-section of different people, not a forecast for you.
Where the clinical cut-off falls here
16.0 kg (35.3 lb) sits at the 5th percentile of this ladder — the lowest published point. Most women this age are well above it.
The 16.0 kg (35.3 lb) EWGSOP2 figure is a screening threshold used by clinicians, not a self-diagnosis. A reading near it means a professional would look further, nothing more. If your number concerns you, that is a conversation with your doctor or physiotherapist — not with a table on the internet. Source: Cruz-Jentoft et al., Age Ageing, 2019.
What a normal left–right difference looks like at this level
At this group's median, an 8.1% left–right difference is about 2.4 kg (5.3 lb). That is one derived number from the pooled figure used sitewide — not a diagnosis, and not a full symmetry analysis. Full breakdown: grip strength symmetry.
The same age band for men has a median of 49.3 kg (108.7 lb).

Your reading is placed on the published percentile ladder for your five-year age group — the same international norms tabulated below (Tomkinson et al., 2025; 2,405,863 adults, 69 countries). Those norms are harmonised to a reference protocol: hydraulic dynamometer, seated, elbow flexed, three squeezes per hand, best result. Test differently and your percentile shifts. Ages under 20 are compared with the 20–24 group, which the source does not cover. Orientation only, not a medical assessment.
FAQ
What is the average grip strength for a 27 year old woman?
The median grip strength for women aged 25–29 is 29.4 kg (64.8 lb), from international norms covering 2.4 million adults.
What is a good grip strength at ages 25–29?
Against this group's ladder, below 24.5 kg (54.0 lb) counts as low for this age band. High starts at 34.6 kg (76.3 lb). The 40th–59th percentile is moderate.
Is 16.0 kg (35.3 lb) a weak grip for women aged 25–29?
16.0 kg (35.3 lb) sits at the 5th percentile of this ladder — the lowest published point. Most women this age are well above it. The 16.0 kg (35.3 lb) figure is a clinical screening cut-off (EWGSOP2), not a diagnosis and not a self-assessment.
Method and limitations
These numbers are the published percentile ladder from Tomkinson GR et al., 2025 — 2,405,863 adults, 69 countries, Table 2, absolute handgrip strength in kg. The norms are harmonised to a reference protocol: hydraulic dynamometer, seated, elbow flexed, three squeezes per hand, best result. Test differently and your percentile shifts. Ages under 20 are compared with the 20–24 group, which the source does not cover. Orientation only, not a medical assessment.
The cross-age chart, why published charts disagree, and where the 27 kg (59.5 lb) / 16 kg (35.3 lb) cut-off comes from stay on the average grip strength by age guide. This page does not repeat them.
