No — 145 lbs is within the healthy range for 5'4".
At 145 lbs (65.8 kg) and 5'4" (162.6 cm), the BMI is 24.9 — normal weight.
For an adult who is 162.6 cm tall, the World Health Organization considers a weight between 108 and 145 kg to be healthy.
Your BMI of 24.9 sits in the normal weight band. Cutoffs: 18.5, 25, 30, 35 (WHO).

What the numbers mean for you
You have 1 lbs (0.3 kg) of headroom before crossing into overweight (BMI 25 = 146 lbs (66.1 kg)).
The arithmetic midpoint of the healthy band at this height is BMI 21.7 (127 lbs (57.4 kg)). That is a midpoint, not a target: there is no evidence that any specific point inside the healthy range is individually optimal.
Timelines assume ~7,700 kcal per kg of body fat. Real progress varies with muscle mass, adherence, and medications.
What this means
Staying inside this band is associated with the most favourable metabolic markers in adult populations under 65.
Waist adds information BMI cannot
Two people can share the same BMI and carry very different amounts of abdominal fat. Waist circumference captures that difference, which is why clinical guidance (NICE CG189, WHO 2008) recommends reading it alongside BMI rather than instead of it.
Waist-to-height rule: guidance suggests keeping waist below half your height — below 81 cm (32") at 162.6 cm.
Sex-specific thresholds: increased risk from 94 cm (37") for men and 80 cm (31.5") for women; substantially increased risk from 102 cm (40") and 88 cm (34.6") respectively. There is no unisex waist threshold.
What it does not do: waist is another screening measurement. It does not diagnose anything. These waist cut-offs were derived mainly from European-origin populations. WHO notes that equivalent risk occurs at lower waist values in South Asian, Chinese, Japanese and other Asian populations, so they are population-specific rather than universal. The waist-to-height rule above is the more portable check (NICE NG246, for adults with a BMI below 35).

Movement, 7–9 hours of sleep and balanced meals are the population-level basics.
Resistance training is what slows age-related muscle loss.
Month-over-month trends are more meaningful than daily fluctuation.
Blood pressure and cholesterol are separate measurements — BMI does not indicate either.
Frequently asked questions
Is 145 lbs overweight for 5'4"?
145 lbs at 5'4" gives a BMI of 24.9, which is normal weight. The healthy range for 5'4" is 108–145 lbs.
Is 145 lbs overweight at 5'4"? The short answer, and how close it is
No — but by 1 lb. At 5'4" (162.6 cm), 145 lbs gives a BMI of 24.9. The overweight threshold at this height is 146 lbs (BMI 25.0), so 145 lbs is the last pound-level reading still inside the healthy band. Each pound at 5'4" is worth 0.1 BMI points.
This is why the same person gets contradictory answers from different calculators: tools that round 5'4" to 163 cm, or that use 703 × lbs ÷ inches² without rounding, land on either side of 25.0. Both are "correct" to their own rounding rule. The honest statement is that 145 lbs at 5'4" sits on the boundary, and no health conclusion should hinge on which side of it a calculator puts you.

The four numbers that define 5'4"
Underweight below 108 lbs (48.9 kg) — you are 37 lbs above it.
Healthy: 108–146 lbs (48.9–66.1 kg) — a 38 lb wide band.
Overweight from 147 lbs — 2 lbs above your current weight.
Obese from 175 lbs (79.3 kg) — 30 lbs away.
Because the healthy band at 5'4" is only 38 lbs wide, weight at this height crosses categories faster than at taller heights. At 5'10" the same band spans about 39 lbs. That compression, not any difference in the body, is why shorter adults hit the overweight label at what feels like a small gain.
Practical reading of a boundary result
Scale timing. A full stomach, a salty dinner, or a menstrual-cycle water shift moves the scale 2–4 lbs, which at 5'4" is 0.2–0.4 BMI points — enough to cross 146 lbs and back within one week without any change in body fat. Use a 7-day average, weighed at the same time of day, rather than a single reading.
Clothing and shoes. Indoor clothes add 1–2 lbs, shoes 1–2 more. A clothed weigh-in at a clinic is the most common reason a home "145" becomes a chart "148".
What actually distinguishes the two sides of the line. At 145 lbs and 5'4", waist circumference is more informative than the last pound. Under 32" (half your height, 81 cm) indicates low central-fat risk; over 35" (88 cm) for women or 40" (102 cm) for men indicates elevated risk regardless of which side of BMI 25 the scale reports.
If the goal is to move away from the boundary. Dropping to 139 lbs gives BMI 23.8 and puts 7 lbs between you and the line — roughly six weeks at a modest 500 kcal daily deficit. There is no evidence that being at BMI 24.9 versus 25.2 changes health outcomes; the reason to create margin is measurement stability, not risk.
Method for this page
5'4" is converted as 64 inches × 2.54 = 162.6 cm, and 145 lbs as 65.8 kg (1 lb = 0.45359 kg). BMI = 65.8 ÷ 1.626² = 24.9. Threshold weights come from WHO cut-offs 18.5, 25 and 30 applied to the same height, then converted back to pounds and rounded to the nearest pound — which is why the overweight line reads 146 lbs rather than an exact decimal. BMI is a screening ratio for adults; it does not measure body fat, and it is not a diagnosis.
