The result screen shows fit information in a few different ways. Here is what each one means.
The fit bar
The fit bar runs from too tight on the left to too loose on the right. The green middle is the range where a garment fits well. Colours mean the same thing on every chart.
If you are seeing a single bar
The bar shows the tightest measurement of that size, not an average. One tight sleeve moves the whole bar left even when everything else is ideal.
Switching on the detailed result view shows each measurement separately and is much easier to interpret.
If you are seeing two sizes with percentages
The percentage is how well the size scored out of the maximum possible. It is not the probability of a good fit and not a fit percentage.
Shoulder and length measurements
Shoulder measurements are scored but not described in words on the result screen. A shoulder fit issue can affect the outcome without appearing in the list.
Lengths only appear when they are out of range.
