What is SizeChecker?

SizeChecker is a module within ScanneryOne that recommends best fitting garment sizes.

Finding the right size is more complex than comparing a single body measurement. The result depends on the correct body measurements, the measurements of the garment and how the garment is intended to fit.

SizeChecker combines all of this information in one process.

ScanneryOne computes body measurements according to ISO standards or according to additional measurement systems and individual customer requirements. SizeChecker compares these measurements with garment data and also takes movement allowance and material stretch into account.

A size recommendation is generated within seconds - for any number of garments at the same time.

How SizeChecker works

SizeChecker works in five steps.

On the left side, the body is scanned (1) and measured (2) according to standards such as ISO 8559-1.

On the right side, the relevant garments are measured (3) and their fit allowences and ease are defined (4).

The system then computes (5) which body measurements fit into each garment size and compares these ranges with the measurements of the scanned person.

What is Fit? Fit describes how a garment is intended to sit on the body
- for example close-fitting, regular or loose, with enough room for movement.

1. Scan the body

The person stands inside the BodyLoop. 32 high-resolution cameras capture the body from different angles instantly. It is completely safe and convenient.

The scan takes only 0.3 seconds. The body is captured without contact and with millimetre-level precision.

Because the scan is so fast, the person only needs to hold the position for a moment. This eliminates the risk of movement and makes every scan perfectly accurate. Once the capture is complete, the person can leave the scanner and the next person can prepare to step in.

2. Measure the body

ScanneryOne computes the required body measurements from the 3D scan.

Depending on the garment type, these may include chest circumference, arm length, back length, waist circumference or many more.

Our standard measurement definitions are strictly according to ISO standard (eg. 8559-1). Additional standards and individual measurement definitions can also be added and stored in the system fast and easy.

ISO 8559-1: An international standard that defines where and how body measurements for clothing are taken. This gives users worldwide a common definition of each measurement.

Digital body model: A three-dimensional representation of the scanned body from which the software computes measurements.

3. Measure the garment

To recommend a size, SizeChecker also needs the measurements of the garments - for every garment and every available size.

These measurements are often represented in size charts and can be transferred into SizeChecker. If measurements are not available, they can be taken directly from the garment manually.

4. Define which body measurements fit the garment

Garment measurements alone are not enough. A jacket needs additional ease allowance so that the person can move comfortably.

Together with the customer, we define how the garment should fit and how much the material can stretch. Based on this information, Sizechecker determines the ideal, minimum and maximum body measurements for each garment size.

For Example

A jacket has a chest circumference of 100 cm. With an ease allowance of 10cm the ideal body chest circumference is 90 cm. We then define that body measurements between 85cm and 95cm are still suitable for the jacket. This range is saved in the SizeChecker. The same process is then applied to all other relevant measurements in all sizes (grading).

Ease Allowance: The difference between the garment measurement and the body measurement. A jacket with a 100 cm chest circumference may be designed for an ideal body chest circumference of 90 cm. The 10 cm difference is the ease allowance.

5. Find the right size

SizeChecker compares the measured body dimensions with the stored garment data.

First, the system checks which sizes fit across all relevant measurements. It then computes how far the body measurements are from the ideal values for each suitable size.

The recommended size is the one with the smallest total deviation according to the predefined rule sets.

The calculation takes only a few seconds. Any number of garments can be checked at the same time - from one jacket to a complete clothing set.

If none of the available sizes meets the defined requirements, SizeChecker shows this as well.

Total deviation: The individual differences between the measured body dimensions and the ideal body dimensions are added together. The smaller the total, the closer the size is to the defined ideal fit.
