📐 Bikini Size Calculation Method
This calculator estimates size using standard ranges for bust/waist/hips and provides separate top/bottom suggestions. (If your site uses MathJax/KaTeX, the formulas below will render nicely.)
Size Determination:
\( \text{Size} = f(\text{Bust}, \text{Waist}, \text{Hip}) \)
\( \text{Size} = f(\text{Bust}, \text{Waist}, \text{Hip}) \)
Unit Conversion:
\( \text{Inches} = \frac{\text{Centimeters}}{2.54} \)
\( \text{Centimeters} = \text{Inches} \times 2.54 \)
\( \text{Inches} = \frac{\text{Centimeters}}{2.54} \)
\( \text{Centimeters} = \text{Inches} \times 2.54 \)
Size Range (example by Bust):
\( \text{XS: Bust} \leq 83\text{cm} \)
\( \text{S: Bust} = 83-88\text{cm} \)
\( \text{M: Bust} = 88-98\text{cm} \)
\( \text{L: Bust} = 98-108\text{cm} \)
\( \text{XL: Bust} = 108-118\text{cm} \)
\( \text{XXL: Bust} > 118\text{cm} \)
\( \text{XS: Bust} \leq 83\text{cm} \)
\( \text{S: Bust} = 83-88\text{cm} \)
\( \text{M: Bust} = 88-98\text{cm} \)
\( \text{L: Bust} = 98-108\text{cm} \)
\( \text{XL: Bust} = 108-118\text{cm} \)
\( \text{XXL: Bust} > 118\text{cm} \)
Measurement Tips: Measure over bare skin or thin clothing. Bust at fullest part, waist at narrowest point, hips at widest part.

💡 How to Measure for Your Bikini
- Bust: Around the fullest part, tape parallel to the floor, snug not tight.
- Waist: Around the narrowest part of your natural waistline.
- High Hip: ~3–4 inches below waist (helps with bottom waistband fit).
- Hips: Around the fullest part of hips/buttocks, feet together.
- Pro Tip: Measure twice for accuracy.
👙 Understanding Bikini Sizing
- Mix & Match: Many brands let you order different top and bottom sizes.
- Bra-Sized Tops: Some tops use band/cup sizing for better support.
- Fabric Stretch: More elastane usually means more forgiveness.
- Brand Variations: Always check the brand’s chart + reviews.
- Style Matters: Coverage/support changes with cut and design.
❓ Frequently Asked Questions
How do I know what size bikini to order?
+
Measure your bust, waist, and hips, then compare to the chart. Your top usually follows bust; your bottom usually follows hips. If between sizes, sizing up is often more comfortable. Separates are ideal if top/bottom sizes differ.
Should I size up or down for bikinis?
+
Between sizes? Size up for comfort. If you want a very snug fit and the fabric is very stretchy, you can consider the smaller size—check brand notes and reviews.
What's the difference between high hip and hip measurements?
+
High hip is measured a few inches below the waist; hips are measured at the fullest point of your buttocks/hips. High hip helps predict how the waistband will sit; hips help predict overall bottom coverage/comfort.
Can I wear different sizes for bikini top and bottom?
+
Yes—super common. If your bust suggests M but hips suggest L, get an M top + L bottom when possible.
How tight should a bikini fit?
+
Snug, secure, and comfortable—no gaping, no digging. Swimwear can loosen when wet and with wear, so slightly snug when new is usually ideal.
Will my bikini stretch out over time?
+
Often yes (roughly 5–10%) depending on fabric, chlorine/salt exposure, and care. Rinse after use, hand wash gently, and air dry to keep shape longer.
🛒 Bikini Shopping Tips
