Size & Fit Guide

Not sure which size to choose? Use the guides below to find your perfect fit for wigs and press-on nails.

Wig Size Guide

Most Trilumity wigs are made with an adjustable average cap size (21″–22.5″ / 53–57cm head circumference), fitting the majority of adult women comfortably thanks to adjustable straps and combs inside the cap.

How to Measure Your Head

  1. Use a soft measuring tape and start at your hairline, front center.
  2. Wrap it around your head above your ears, following your natural hairline, back to the starting point.
  3. Note the measurement in inches — this is your head circumference.
Head Circumference Wig Cap Size Fits
20″ – 21″ Petite / Small Smaller frame, petite build
21.5″ – 22.5″ Average (most Trilumity wigs) Majority of adult women
23″ and up Large Fuller head shape

Lace Size Guide (Lace Front & HD Lace Wigs)

  • 4x4 Lace Closure: Covers the front hairline area only — ideal for simple parting styles.
  • 13x4 Lace Frontal: Ear-to-ear coverage, allows deep side parts and pulled-back styles.
  • 13x6 Lace Frontal: Extended hairline coverage for the most natural-looking baby hair and the most versatile parting.

Hair Length Guide

Length Approx. Placement
10″–12″ Chin to shoulder (bob length)
14″–16″ Shoulder to collarbone
18″–20″ Mid-back
22″–24″ Waist length
26″+ Below waist

Nail Size Guide

Trilumity press-on nail sets typically include 10–24 tips per box, covering multiple sizes so you can find the closest match for each of your 10 nails.

How to Measure Your Nails

  1. Measure the width of your natural nail bed (cuticle to cuticle) at its widest point, side to side.
  2. Compare your measurement to the size chart below for your closest match.
  3. If a tip is slightly too wide, gently file the sides down for a custom fit. Avoid sizes that are too narrow — they can pinch or lift.
Size Approx. Width Typical Finger
0 (XS) 10mm Pinky
1 11mm Pinky / Ring
2 12mm Ring
3 13mm Ring / Middle
4 14mm Middle
5 15mm Middle / Index
6 16mm Index
7 (XL) 17mm+ Thumb

Choosing a Length & Shape

  • Short / Medium: Best for everyday wear, typing, and an easy first-time press-on experience.
  • Long: A dramatic, glam look for special occasions.
  • Shapes: Almond and coffin lengthen the fingers; square and round offer a natural, low-maintenance look.
