What is Pregnancy Weight Gain?
The Pregnancy Weight Gain calculation tells you your recommended gain – upper from a few simple inputs. The figure you are solving for here is the recommended gain – upper.
The Pregnancy Weight Gain formula
This calculation combines several inputs through a multi-step method rather than a single one-line formula. Enter the values below and the calculator resolves each step in order. The inputs it needs are:
- Pre-pregnancy weight — a value measured in kg. Example: 60 kg.
- Height — a value measured in cm. Example: 165 cm.
How to calculate it step by step
- Write down the pre-pregnancy weight (for example, 60 kg).
- Write down the height (for example, 165 cm).
- Apply the formula above to get your recommended gain – upper.
- Double-check the result with the Pregnancy Weight Gain Calculator.
Worked examples
Example 1
| Input / Output | Value |
|---|---|
| Pre-pregnancy weight | 60 kg |
| Height | 165 cm |
| Recommended gain – upper | 16.0 |
| Recommended gain – lower | 11.5 |
| Pre-pregnancy BMI | 22.0 |
With pre-pregnancy weight of 60 kg and height of 165 cm, the recommended gain – upper works out to 16.0.
Example 2
With pre-pregnancy weight of 120 kg and height of 165 cm, the recommended gain – upper works out to 9.0.
| Result | Value |
|---|---|
| Recommended gain – upper | 9.0 |
| Recommended gain – lower | 5.0 |
| Pre-pregnancy BMI | 44.1 |
Example 3
With pre-pregnancy weight of 30 kg and height of 165 cm, the recommended gain – upper works out to 18.0.
| Result | Value |
|---|---|
| Recommended gain – upper | 18.0 |
| Recommended gain – lower | 12.5 |
| Pre-pregnancy BMI | 11.0 |
Tips for an accurate result
- Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
- Round only at the very end. Rounding inputs early can shift the final answer noticeably.
- Re-run the numbers whenever an input changes, rather than estimating from an old result.
- These figures are general estimates, not medical advice — check with a qualified professional before acting on them.
