Frequently Asked Questions

How accurate are these size calculators? ▼
Our size calculators use industry-standard formulas developed by lingerie and clothing professionals. Accuracy depends on precise measurements. To ensure the best results, measure yourself carefully following our guidelines, and consider that different brands may fit slightly differently. When possible, compare your calculated size with brand-specific sizing charts for additional confirmation.
What if my calculated size doesn't match what I usually wear? ▼
Sizing discrepancies often occur because many people wear the wrong size. If your calculated size differs significantly from your usual size, try the recommended size first. Factors like bra cup size migration (where larger bands correspond to smaller cups and vice versa) might explain the difference. Many people find their correct size is actually different from what they've been wearing.
Why do sizes vary between brands and countries? ▼
Different countries developed their own sizing standards independently. The USA uses numeric sizes (32, 34, etc.) while Europe uses letters (AA, A, B, etc.). Additionally, individual brands set their own fit models, meaning sizing varies between manufacturers. Our calculators help you navigate these differences by providing conversions and brand-specific recommendations.
Should I remeasure regularly? ▼
Yes, it's recommended to remeasure yourself every 1-2 years, or whenever you experience significant weight changes. Your body changes over time due to age, fitness levels, and other factors. Periodic remeasurement ensures you always have the most accurate size for optimal comfort and fit in new purchases.
Is my personal data safe when using these calculators? ▼
Yes, your data security is our priority. These calculators perform all calculations in your browser without sending your measurements to any external servers. Your personal measurements are never stored, recorded, or shared. You can use these tools with complete confidence in your privacy.
Can these calculators be used for swimwear and athletic wear? ▼
While primarily designed for apparel and intimate wear, the measurement-based approach of our calculators provides useful size guidance for many clothing categories. However, swimwear and athletic wear often use brand-specific sizing. Always cross-reference with the specific brand's sizing chart for the most accurate fit, as stretch and design vary considerably in these categories.
How do I know if my bra band size is correct? ▼
Your bra band should sit parallel to the ground at the back, not ride up. It should be snug enough that you can fit one finger underneath, but not so tight that it leaves marks or causes discomfort. If your band rides up significantly, you may need a tighter (smaller) size. If it leaves red marks or feels restrictive, try a larger (looser) size. Our bra calculators account for these factors.
What measurements do I need to take? ▼
Required measurements vary by calculator but typically include: for bra sizing—underbust (band) and bust measurements; for dress sizes—bust, waist, and hip measurements; for specialized items—height and weight may also be considered. Each calculator clearly specifies which measurements are needed before you use it. Our "How to Measure Bra Size" guide provides detailed instructions with visual guidance.
