Redi Tape Body Measurement Tape

Flexible retractable tape for waist, hip, chest measurements. Useful alongside weight for tracking changes in body shape.

💡 Editor's note: Weight alone is a poor fitness metric. Tracking waist circumference alongside weight reveals fat loss vs muscle gain. A tape measure is inexpensive and can tell you more than a scale upgrade.

What to look for

For most people: any accurate digital scale plus a measuring tape is more informative than a smart scale alone. Smart scales estimate body fat via bioimpedance — the readings vary with hydration and time of day. Use them for trends, not absolute values.

Frequently asked

?

Are smart scales accurate for body fat?

Not clinically, but usefully. Bioimpedance estimates can differ from DEXA scans by several percentage points, and vary with hydration. Consistency matters more than accuracy — weigh at the same time every day (morning, after bathroom, before eating) to get comparable readings.

?

Which unit should UK scales display?

Most UK scales display kg, stones+lbs, and lbs. For medical/clinical use, kg is standard. Most UK adults still think of their weight in stones and lbs for personal reference.
