Body Measurements
Track waist, chest, hips, arms and thighs over time.
Overview
The Body Measurements tracker captures the circumferences that the bathroom scale never tells you. Waist, chest, hips, arms, and thighs each move on their own timeline, and watching them together gives a far richer picture of recomposition than weight alone. Lifters chasing hypertrophy, runners watching for unwanted muscle loss, and anyone working through a calorie deficit will see in tape-measure numbers what a scale routinely hides.
You can log any subset of the five measurements at any cadence; the tool does not nag you to fill in every column. Each row is timestamped and editable, so the record builds into a longitudinal view of how your shape is responding to training, nutrition, and recovery choices over weeks and months.
How it works
Measurements are stored internally as centimetres regardless of the unit you type in. A unit toggle at the top lets you enter inches if that is your reference; the tool converts using the exact 2.54 cm per inch factor and renders historical rows in the unit you currently have selected, so switching between metric and imperial never loses precision.
Inputs accept tenths of a unit. Empty fields are stored as null rather than zero so a partial entry, for example only waist and hips on a given week, does not skew totals or charts. Each row can be deleted individually, and only the most recent few weeks are shown in the list view to keep the page fast on long histories.
Examples
- Cutting phase: log waist weekly to confirm the deficit is producing the expected one to two centimetre drop per month while chest and arms hold steady.
- Bulking phase: track arm and chest growth alongside waist to gauge whether the surplus is going to muscle or fat.
- Post-injury return: monitor the affected limb against the opposite side to quantify atrophy recovery during physiotherapy.
- Apparel and tailoring: capture a baseline before a wardrobe refresh so sizes ordered online match your current shape.
FAQ
Where exactly should I place the tape? Be consistent rather than perfect. Waist is usually at the navel, hips at the widest point, arms at the mid-bicep relaxed, thighs at the largest point below the gluteal fold, chest at nipple line on a relaxed exhale. Take a photo of your reference points so you can replicate them.
How often should I measure? Weekly is enough signal without daily noise. Same time of day, same hydration state, ideally on waking before food or water.
Why store everything in centimetres? A single canonical unit avoids rounding drift when you toggle the display between inches and centimetres across months of entries.
Can I skip fields? Yes. Leave any measurement blank and the row will save the rest. Missing entries are not treated as zeros.
