Knowing whether your cattle are at the right weight for their age and breed is one of the most practical management tools available to any producer. A calf that is significantly underweight at weaning signals a health, nutrition, or management problem. A heifer that has not reached 60–65% of her mature weight before breeding will underperform reproductively. A steer that falls short of expected market weight costs money on the pen and in the sale ring.
This article provides reference weight charts for the major US cattle breeds by age and sex, explains what drives the differences between breeds, and covers the key weight benchmarks every producer should know — weaning weight, yearling weight, breeding weight, and finished market weight. For producers who need to estimate cattle weight without access to a scale, see our article on how to estimate cattle weight without a scale.

Why Cattle Weight Varies So Much Between Breeds
Before using any weight chart as a management reference, it is important to understand the three variables that drive weight differences between individual animals — and why a single “average cow weight” figure is almost meaningless without context.
Frame size is the primary structural driver of weight. As confirmed by Texas A&M Beef Skillathon, the Beef Improvement Federation (BIF) Frame Score system — based on hip height at a given age — predicts mature weight reliably across breeds. Each Frame Score unit represents approximately 2 inches of hip height difference and roughly 100–115 lb of mature weight difference. A Frame Score 7 Charolais cow will weigh substantially more than a Frame Score 4 Angus cow of the same age, even in identical body condition.
Sex affects both the rate of maturity and mature weight. Bulls reach greater mature weights than steers, and steers reach greater mature weights than heifers of equivalent genetics. As noted by the University of Wisconsin Extension, if frame size is equal, heifers will mature quicker than steers — reaching puberty at a lower percentage of their mature weight.
Body condition can shift a mature cow’s apparent weight by 400 lb or more without any change in actual frame size. As Texas A&M notes, a mature cow weighing 1,200 lb in medium fatness or body condition weighs about 900 lb when extremely thin and 1,600 lb when extremely fat. All weight figures in this article assume moderate body condition (BCS 5) unless otherwise noted.
Average Mature Cow Weight by Breed
These are average mature cow weights at BCS 5 for the most common US beef and dairy breeds. All figures represent cows aged 4–7 years, the age range at which most breeds reach full mature weight.
| Breed | Type | Average Mature Cow Weight (lb) | Weight Range (lb) |
|---|---|---|---|
| Angus | British beef | 1,150–1,350 | 1,000–1,600 |

Average Mature Bull Weight by Breed
Bulls are significantly heavier than cows of equivalent genetics — typically 25–35% heavier at maturity.
| Breed | Average Mature Bull Weight (lb) | Weight Range (lb) |
|---|---|---|
| Angus | 1,800–2,200 | 1,600–2,500 |
| Hereford | 1,700–2,100 | 1,500–2,400 |
| Simmental | 2,000–2,400 | 1,800–2,700 |
| Charolais | 2,100–2,500 | 1,900–2,800 |

Cattle Weight Reference — Metric Conversions
For producers in Canada, Australia, the United Kingdom, and New Zealand working in metric units, the following conversion table provides the breed averages from this article expressed in kilograms. To convert any pound figure to kilograms divide by 2.205.
Average Mature Cow Weight — Metric (kg)
| Breed | Average Mature Cow Weight (kg) | Weight Range (kg) |
|---|---|---|
| Angus | 520–615 kg | 455–725 kg |
| Hereford | 500–590 kg | 455–680 kg |
| Simmental | 590–680 kg | 500–815 kg |
| Charolais | 635–725 kg | 545–860 kg |
| Limousin | 545–635 kg | 475–750 kg |
| Brahman | 455–590 kg | 365–680 kg |
| Brangus | 500–590 kg | 430–680 kg |
| Holstein | 590–680 kg | 500–770 kg |
| Jersey | 365–455 kg | 315–500 kg |
Average Mature Bull Weight — Metric (kg)
| Breed | Average Mature Bull Weight (kg) |
|---|---|
| Angus | 815–1,000 kg |
| Hereford | 770–955 kg |
| Simmental | 910–1,090 kg |
| Charolais | 955–1,135 kg |
| Brahman | 725–910 kg |
The Heart Girth Formula in Metric Units
For producers measuring in centimetres and kilograms, the heart girth formula adapts as follows:
(Heart Girth in cm)² × Body Length in cm ÷ 10,815 = Estimated Weight in kg
Worked example: A mature Angus cow with a heart girth of 183 cm and body length of 142 cm:
183 × 183 × 142 ÷ 10,815 = 4,755,594 ÷ 10,815 = 440 kg estimated weight
For the complete step-by-step guide to taking heart girth and body length measurements correctly — including common technique errors that reduce accuracy — see our article on how to weigh a cow.
Cattle Weight by Age — Growth Benchmarks
These are the weight benchmarks most commonly used in US beef cattle production management. All figures represent Angus and Angus-cross cattle at moderate body condition unless noted — the most common beef breed composition in the US.
Calves — Birth to Weaning (0–7 Months)
| Age | Steer Weight (lb) | Heifer Weight (lb) | Notes |
|---|---|---|---|
| Birth | 65–95 | 60–85 | Varies significantly by breed and dam size |
| 30 days | 150–200 | 130–180 | |
| 60 days | 225–290 | 200–260 | |
| 90 days | 300–380 | 270–340 | |
| 120 days | 380–470 | 340–420 | |
| 150 days | 460–560 | 410–500 | |
| 180 days (weaning) | 540–650 | 480–575 | USDA average weaning weight: 573 lb (steers) |
Weaning weight target: Most US cow-calf operations wean at 150–210 days. As confirmed by USDA NASS, the national average weaning weight for beef calves is approximately 540–580 lb for steers and 490–530 lb for heifers, though this varies significantly by region, breed, and management system.
Average Daily Gain (ADG) at weaning: Well-managed calves on creep feed should gain 2.5–3.5 lb per day from birth to weaning. As the Drovers report on OSU Purebred Beef Center calves confirmed, high-growth-potential Angus bulls achieved ADG of 3.83–4.1 lb/day at 219–258 days of age, while heifers achieved 2.9–3.2 lb/day.
Growing Cattle — Post-Weaning to Yearling (7–14 Months)
| Age | Steer Weight (lb) | Heifer Weight (lb) | Notes |
|---|---|---|---|
| 7 months (weaning) | 540–650 | 480–575 | |
| 8 months | 590–720 | 520–630 | |
| 9 months | 650–790 | 565–690 | |
| 10 months | 710–860 | 615–750 | |
| 11 months | 775–930 | 665–810 | |
| 12 months (yearling) | 840–1,000 | 715–870 | |
| 14 months | 950–1,100 | 800–960 | Heifer breeding target weight |
Key milestone — yearling weight: Yearling weight is one of the most important performance indicators in beef cattle. As noted by the American Angus Association, yearling weights for Angus cattle have increased by 96 lb since the 1970s due to improved genetics and management. The current Angus adjusted yearling weight benchmark is approximately 1,050–1,100 lb for steers.
Breeding Heifers — Weight Target Before First Breeding
Heifer breeding weight is one of the most consequential weight benchmarks in cow-calf production — because a heifer that is too light at breeding will fail to cycle, fail to conceive, or produce a weak first calf.
As confirmed by the University of Wisconsin Extension, heifers should weigh 60–65% of their expected mature weight at first breeding — typically at 14–15 months of age.
| Breed | Expected Mature Cow Weight (lb) | Target Breeding Weight at 14–15 Months (lb) |
|---|---|---|
| Angus | 1,200 | 720–780 |
| Hereford | 1,150 | 690–750 |
| Simmental | 1,400 | 840–910 |
| Charolais | 1,500 | 900–975 |
| Brahman | 1,150 | 690–750 |
| Brangus | 1,200 | 720–780 |
Why this benchmark matters: A heifer at 55% of mature weight at breeding has significantly lower conception rates than one at 65%. The extra 60–80 lb difference between an underweight heifer and a target-weight heifer has a direct impact on the calving percentage and ultimately the economic return of the cow-calf enterprise.
Feedlot and Market Cattle — Finishing Weights
| Cattle Type | Typical Placement Weight (lb) | Typical Finished Weight (lb) | Days on Feed |
|---|---|---|---|
| Angus steer | 700–850 | 1,250–1,400 | 140–180 days |
| Angus heifer | 650–750 | 1,100–1,250 | 120–160 days |
| Charolais cross steer | 800–950 | 1,350–1,550 | 150–190 days |
| Brahman cross steer | 700–850 | 1,150–1,350 | 150–200 days |
| Holstein steer | 500–700 | 1,300–1,500 | 200–240 days |
The 2026 finishing weight trend: As reported by Drovers, research from Kansas State University’s “Focus on Feedlots” project showed that today’s fed cattle are approximately 150–170 lb heavier at finishing than in 1990 — roughly 14% heavier. Modern Angus and Angus-cross steers regularly finish at 1,350–1,450 lb, compared to the 1,200–1,250 lb average of the early 1990s.
Carcass and Hanging Weight Reference
For producers selling on the rail or direct-to-consumer, the relationship between live weight and carcass yield is a critical commercial calculation.
| Live Weight (lb) | Estimated Hot Carcass Weight (lb) | Estimated Dressing Percentage |
|---|---|---|
| 1,000 | 600–630 | 60–63% |
| 1,100 | 660–693 | 60–63% |
| 1,200 | 720–756 | 60–63% |
| 1,300 | 780–819 | 60–63% |
| 1,400 | 840–882 | 60–63% |
| 1,500 | 900–945 | 60–63% |
Dressing percentage is the ratio of hot carcass weight to live weight. The typical range for beef cattle is 60–63%, depending on body condition, fill at weighing, and breed. British breeds like Angus tend toward the higher end of this range. Dairy breeds and Brahman-influenced cattle often yield slightly lower dressing percentages.
The Weight Gain Numbers That Matter for Herd Management
Understanding daily gain targets helps producers identify animals that are falling behind — before the weight deficit becomes a management crisis.
Target Average Daily Gain (ADG) by production stage:
| Stage | Target ADG (lb/day) |
|---|---|
| Nursing calf (birth to weaning) | 2.0–3.0 |
| Backgrounding — grass (weaning to 12 months) | 1.5–2.5 |
| Backgrounding — grain supplement | 2.0–3.0 |
| Feedlot finishing | 3.0–4.0 |
| Replacement heifer development | 1.5–2.0 |
An animal gaining below the lower threshold for its production stage is a signal requiring investigation — whether that is nutritional deficiency, parasite load, illness, or genetic underperformance. For the complete guide to tracking cattle weight gain over time using a livestock scale, see our article on how to track cattle weight gain.
How to Use a Livestock Scale to Capture These Benchmarks
A weight chart is only useful if you have an accurate weight to compare against it. Estimating cattle weight by eye — even by experienced producers — carries a typical error of 5–10%, which is enough to miss a breeding weight benchmark or miscalculate a medication dose.
The practical approach for most operations is to weigh at four key points:
- Birth: Calf birth weights are strongly correlated with future performance and calving ease in subsequent generations. A birth weight record on every calf is the foundation of a genetic improvement program.
- Weaning: Weaning weight adjusted for age and dam age is the primary performance indicator for the cow-calf enterprise. Accurate weaning weights require a calibrated livestock scale — not an estimate.
- Pre-breeding: Heifers should be weighed 60 days before the intended breeding date to confirm they are on track to reach 60–65% of mature weight. Those falling short need supplemental nutrition — not a guess.
- Pre-sale or pre-slaughter: The most commercially consequential weighing event for most operations. The difference between an accurate scale weight and an estimated weight at market is real money.
For the full guide to selecting the right livestock scale for your operation — including weigh bar systems, cage systems, and portable options — see our complete guide to farm and livestock scales.
Estimating Cattle Weight When a Scale Is Not Available
When a livestock scale is not accessible — at a remote paddock, at an auction, or in a field emergency requiring medication dosing — the heart girth formula provides a reasonable weight estimate for cattle.
The heart girth formula:
Weight (lb) = (Heart Girth in inches² × Body Length in inches) ÷ 300
For the complete step-by-step guide to using this formula correctly — including how to measure heart girth and body length accurately, worked examples for different breed sizes, and when estimation is not sufficient — see our article on how to estimate cattle weight without a scale.
FAQs
What is the average weight of a beef cow?
A mature beef cow in moderate body condition (BCS 5) typically weighs 1,100–1,400 lb, depending on breed and frame size. British breeds like Angus and Hereford average 1,150–1,300 lb. Continental breeds like Charolais and Simmental average 1,300–1,600 lb. Brahman and Brahman-influenced cows average 1,000–1,300 lb.
How much does a calf weigh at birth?
Most beef calves weigh 65–95 lb at birth. Bull calves are typically 5–10 lb heavier than heifer calves at birth. Birth weight varies significantly by breed — Continental breeds like Charolais tend to produce heavier calves than British breeds like Angus, which is one reason Angus is commonly used as a calving-ease breed in first-calf heifer programs.
How much should a heifer weigh before breeding?
A replacement heifer should weigh 60–65% of her expected mature weight at first breeding — typically at 14–15 months of age. For an Angus heifer with an expected mature weight of 1,200 lb, the target breeding weight is 720–780 lb. Heifers below this target have significantly lower conception rates.
What is the average slaughter weight for cattle in the US?
As confirmed by USDA NASS data, US fed cattle today finish at approximately 1,350–1,450 lb for steers and 1,200–1,300 lb for heifers — roughly 150–170 lb heavier than the early 1990s average, reflecting improvements in genetics, nutrition, and days on feed.
How much does a yearling steer weigh?
A well-managed Angus or Angus-cross yearling steer at 12 months should weigh approximately 840–1,000 lb, depending on weaning weight, post-weaning nutrition, and genetic potential. High-performance genetics and intensive nutrition can push yearling weights to 1,100 lb or above in commercial feedlot programs.
What is the dressing percentage in cattle?
Dressing percentage is the ratio of hot carcass weight to live weight, expressed as a percentage. Most beef cattle yield a dressing percentage of 60–63%. A 1,300 lb steer with a 62% dressing percentage produces approximately 806 lb of hot carcass weight.
Conclusion
Cattle weight benchmarks — at birth, weaning, yearling, breeding, and market — are the reference points that separate informed management decisions from guesswork. A calf below the weaning weight target, a heifer below the breeding weight target, or a steer below the expected yearling weight are all problems that a scale and a chart identify early enough to act on.
The figures in this article represent averages across well-managed herds of the named breeds under moderate nutritional conditions. Individual animals and individual herds will vary — the value of these benchmarks is not to judge every animal against them, but to identify when the gap between your herd’s performance and the expected range is large enough to warrant investigation.
Accurate, reliable weight data requires a calibrated livestock scale at key production events. For the complete guide to choosing, setting up, and using a livestock scale, see our farm and livestock scales guide.
