Maintenance Calories for a 5 Foot 4 Woman
At 5'4, maintenance runs from roughly 1,600 to 2,500 calories a day — and deficits need extra care at that scale.
At a glance
A Concrete Reference Point
For a 5 ft 4 in (162.6 cm) woman weighing 140 lb (63.5 kg) at age 30, the Mifflin-St Jeor equation gives a BMR of 10 × 63.5 + 6.25 × 162.6 − 5 × 30 − 161 ≈ 1,340 kcal/day. Multiply by activity and her maintenance — the intake that holds her weight steady — ranges from about 1,608 to 2,546 kcal/day. Enter your own weight and age above, since both move the number meaningfully.

Maintenance by Activity Level
| Activity Level | Maintenance (kcal/day) |
|---|---|
| Sedentary (×1.2) | 1,608 |
| Lightly active (×1.375) | 1,842 |
| Moderately active (×1.55) | 2,077 |
| Very active (×1.725) | 2,312 |
| Super active (×1.9) | 2,546 |
Cutting Safely From a Smaller Base
Smaller maintenance numbers make aggressive deficits dangerous. From 1,608 kcal of sedentary maintenance, a 500-calorie deficit lands at 1,108 kcal — below the 1,200 kcal daily floor generally recommended for women without medical supervision. The better move is a 250-calorie deficit, targeting about 1,358 kcal/day for roughly half a pound of loss per week, or raising activity so maintenance — and the safe deficit — both rise. A lightly active version of the same woman can eat 1,592 kcal and still lose a pound a week.
How Age and Weight Move the Target
Each year of age subtracts 5 kcal from BMR, so the same woman at 50 maintains about 100 kcal lower than at 30. Each 10 pounds of body weight shifts BMR by roughly 45 kcal — down as she loses, up as she gains. Recalculate every few weeks during a diet; the maintenance number that was right in month one is too high by month three.
Frequently Asked Questions
Why do shorter women need fewer calories?
Calorie needs scale with body size. Less height means less body mass to power, so BMR is lower — about 6.25 fewer calories per day for every centimeter of height.
Can I eat 1,200 calories a day?
1,200 kcal is the commonly cited minimum for women dieting without medical supervision. Below that, covering protein and micronutrient needs becomes very difficult, so most 5'4 women should plan deficits around or above that floor.
Does weight or height matter more for maintenance?
Weight, by a wide margin: the equation gives 10 kcal per kilogram of weight versus 6.25 per centimeter of height. That is why recalculating as your weight changes matters so much.
How do I raise my maintenance calories?
Move more — each activity level step is worth roughly 200–250 kcal per day at this body size — and build muscle through resistance training, which raises resting burn modestly over time.
