FIT SCHOOL · MANUAL MEASUREMENT

Measure first. Choose with evidence.

A clear product photo can show shape and color. Only manual measurements and an approved product chart can narrow physical size.

SORLA FIT SCHOOL

Three measurements bring you closer to the right cap.

Manual tape measurements guide physical sizing. Photo previews are only for appearance.

  3. 3Return to start
How to choose a size

Compare circumference, front-to-nape and ear-to-ear together. Do not use circumference alone.

If your numbers span sizes

Do not force a size. Save the measurements for human review and consider an adjustable cap or custom fit.

SORLA PARTIAL FIT SCHOOL

Use the fit route made for the product.

Women’s toppers use curved base measurements. For men’s hairpieces, prepare a clear crown photo and complete the fit details required by your order.

A topper must cover the thinning area while its clips sit on supportive biological hair around the perimeter.

  2. 2Trace both side boundaries
  3. 3Close the shape behind the crown
When curved measurements may be enough

A regular stock base can be reviewed from the exact curved length and width, but only against that supplier’s confirmed size rule.

When a template is required

Use a template or approved previous unit for an irregular outline, custom hairline, unusual scalp curve or made-to-measure base.

CHECK THE EXACT PRODUCT BASE BEFORE ORDERING

Never add a universal margin. Attachment, base material and factory cutting rules vary by product.

Payment never releases a hair product straight to production.

  1. 01 · Order recorded

    Your exact product, color and Comfort or Sport profile are saved.

  2. 02 · Fit details submitted

    Complete the requested measurements in your account and submit them from the order. This page’s photo preview does not replace that step.

  3. 03 · Human review

    A specialist checks measurements, outline, attachment and the supplier’s exact base rule.

  4. 04 · Fit locked

    Only an approved, customer-confirmed specification can be released for production and shipping.

Production boundary: no custom production begins until the order-specific fit is locked. Cancellation, change and remake eligibility follow the policy shown for the order.

BEFORE YOU START

Make the measurement repeatable.

Use the same method each time so the saved numbers remain useful for product comparison and human review.

  1. Use a soft measuring tape

    Measure in centimeters and keep the tape flat against the head.

  2. Prepare the hair

    Flatten bulky hair and remove accessories without compressing the head.

  3. Measure more than once

    Repeat every route two or three times and record the consistent value.

  4. Check the exact product chart

    Size names are not universal. Never transfer one supplier's SS, S, M or L to another product.

About the reference size values

The supplied reference mentions SS, standard and large examples but does not provide a complete verified four-size chart. SORLA therefore teaches the measurement method without turning those illustrative values into a purchase recommendation. A verified chart must be attached to each made-to-fit SKU before production.
