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
- Use a soft measuring tape and start at your hairline, front center.
- Wrap it around your head above your ears, following your natural hairline, back to the starting point.
- 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
- Measure the width of your natural nail bed (cuticle to cuticle) at its widest point, side to side.
- Compare your measurement to the size chart below for your closest match.
- 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.
