Why is one client getting inaccurate body fat or biometric results when everyone else scans fine?

When only one client shows inaccurate results, the scanner itself is not the problem. The issue is almost always related to how that specific client stands during the scan, what they are wearing, or physical characteristics that affect how the camera reads their body. A few simple adjustments will usually resolve this.

Step 1: Verify the Client's Height and Weight Are Entered Correctly

An incorrect weight or height value on file can directly affect body fat % and other biometric measurements. Before investigating hardware or environment, confirm these values are correct:

1. Open the client's scan in Styku Studio.
2. Navigate to the Body Metrics tab and locate the Body Composition section — the recorded weight and height are listed here.
3. If you are comparing two scans (e.g., a progress scan), use the drop-down menu at the top of the 3D view to switch between scans and verify the values for each.
4. If either value is incorrect, go to Settings > Edit Scan to correct the scan information.

Step 2: Check the Client's Positioning

How a client stands has the biggest impact on measurement accuracy. Before the next scan, make sure the client:

1. Steps onto the center of the turntable platform — not toward the edge.
2. Stands up straight with their weight evenly distributed on both feet.
3. Places their feet approximately shoulder-width apart.
4. Holds their arms slightly away from their sides — arms resting against the body can cause the scanner to miss measurements in that area.
5. Stays completely still and looks straight ahead for the full scan.

Posture must be consistent across sessions — inconsistent posture between scans is a known cause of measurement variability.

Step 3: Check What the Client Is Wearing

Clothing choice significantly affects how the infrared camera captures the body shape. Clothing must also be consistent between scans for progress comparisons to be meaningful.

• Wear form-fitting clothing — compression shorts, sports bras, fitted leggings, or swimwear are ideal.
• Avoid loose or baggy clothing — the scanner reads the outer surface of whatever is visible, so loose fabric will be measured as part of the body.
• Avoid reflective or metallic fabrics — these can interfere with the infrared depth sensor.
• Remove shoes and thick socks — bare feet or thin socks give more accurate foot and lower-leg measurements.
• Remove bulky accessories — belts, large jewelry, or hair worn in a high bun can affect results.

Step 4: Check the Scanning Environment

Even if the room setup works for other clients, double-check these conditions before scanning this client again. Note that scans should always be captured in the same location — scanning in different environments can itself introduce measurement inconsistencies between sessions.

• No direct sunlight or bright ambient daylight entering the scan area. Natural light interferes with the infrared camera.
• No reflective objects near the scan area — mirrors, glass surfaces, and similar objects can cause measurement errors.
• Ensure there is a backing wall behind the client — scanning without a wall behind the subject can affect results.
• No objects or furniture within the immediate scan area on any side of the turntable.
• No shadows or strong backlighting falling directly on the client during the scan.

Step 5: Restart the System and Rescan

If the environment and positioning look correct, do a fresh restart before scanning this client:

1. Close Styku Studio on the laptop.
2. Power off the turntable using its power adapter.
3. Unplug both USB cables (camera tower and turntable) from the laptop.
4. Restart the laptop.
5. Reconnect both USB cables and power on the turntable.
6. Open Styku Studio and attempt the scan again.

When to Contact Support

If you have tried all the steps above and this client still receives inaccurate results, the Styku support team can review the actual scan data and investigate further.

If this resolves your issue, no further action is needed.

If the problem persists, contact support and include: the client's full name and profile ID in Styku Studio, the date and time of the affected scan(s), a description of what the client was wearing and how they were positioned, and whether a rescan was attempted and what the result was.

Applies to: Styku Studio V5, all Styku scanner models (X2L, X2, X2 Pro, S100)
