Start with the patch of scalp you want the topper to cover. Measure it front to back and side to side, then compare both measurements with the shape of the base. Before you settle on a size, check where the clips would land. A base can cover the entire area and still be a poor fit if the clips would sit on hair that feels too sparse or fragile to hold them comfortably.
On an EWIGSC product page, a 14-inch topper describes the hair length. The separate base measurements tell you how much room the piece takes up on top of your head.
Find the area you actually want to cover
Part your dry hair the way you wear it most days. Take one photo from above and another from behind in indirect daylight. The rear view helps you see whether the thinning stops along the part or continues into the crown, around the spot where your hair changes direction.
- A widening part. Follow the visible strip of scalp from front to back. Check its widest point too. A narrow base is a reasonable first comparison when the surrounding hair gives you room to attach the clips.
- A thinning crown. Check how far the area extends to each side of the whorl and how far back it reaches. A piece that covers the part from the front may still leave the back of the crown showing.
- A part and crown that run together. Measure the full span you want covered. Compare broader bases first, and look closely at whether the hair near the outer attachment points can support a clip.
Take two measurements and compare the outline
Use the lines to see the two measurement directions. Start and stop at the edges of your own coverage area, which may begin behind the hairline or extend past the crown whorl.
- With a soft tape, measure along the curve of your head from the front edge of the area you want covered to its back edge.
- Measure across the area at its widest point. If one side extends farther than the other, note that on your photo. A length and width alone won't show where that extra coverage is needed.
- Compare the measurements with a top-down view of the base. Check which dimension runs front to back and how much the base narrows at the ends. If you have a correctly scaled outline or template, hold it over the area with the front facing forward. Keep the measurements and the outline as two checks on the same fit.
- Look beyond the area you want covered to where the clips would sit. Use the product's inside view when it shows the clip layout. If there is no clear view and a clip could land on the sparse area, confirm the layout before ordering.
For example, if the area measures 3.5 inches across at the crown, a base only 3 inches wide at that point falls short, even if it reaches far enough back. A wider base stays on the shortlist. Its shape and clip positions still matter. The American Hair Loss Association explains why sizing varies with the shape of the thinning area, the base construction and the available attachment hair.

Compare EWIGSC base sizes
The drawing illustrates how coverage can widen across the top of the head. Use the listed dimensions below to narrow your options before checking the actual base outline and clip placement.
| Coverage option | Listed base dimensions | Hair length and texture | When to compare it |
|---|---|---|---|
| Part Coverage | 11 × 7.5 cm, about 4.3 × 3.0 in | 14 in, straight | The area is concentrated around the part and has little spread to either side. |
| Crown Coverage | 4 × 4.8 in | 14 in, straight | You want more width through the top while keeping a straight finish. |
| Full Crown Coverage | 6 × 6.5 in | 12 or 14 in, wavy | The area extends across more of the top and crown, and a wave works with the hair you plan to leave visible. |
The two wavy toppers have the same listed base size. If that size fits, compare the lengths by where you want the waves to end alongside your own hair. If you need the largest listed base and want straight hair, the current straight options have smaller bases. Check whether either actually covers your measurements before choosing it for the texture.

When a bigger base helps and when to stop sizing up
Move up a size if the smaller base leaves part of the target area exposed or if the larger shape puts the clips beyond the sparse section. If the bigger base still puts a clip where your hair cannot support it comfortably, another size alone may not solve the problem. A different attachment or a full wig instead of a topper may better suit the coverage you want.
Once you have a likely match, check the fit during your first try-on. Start with the base resting in position and check the back as well as the front. Open any clip that pulls when you move your head. If shifting the piece exposes the area you bought it to cover, take another look at the shape and clip layout before deciding to keep it.
Questions before ordering
Should I add half an inch to my measurements?
Use your measurements to rule out bases that are clearly too small. How much extra room you need depends on where the base tapers and where its clips sit. Compare those details on the specific piece before picking a size.
Can I move a narrow topper farther back to cover my crown?
Only if the crown is the area you need to cover and the clips still have suitable hair to grip. Check the front in the mirror after moving the piece. If the part you wanted covered is now visible, look for a base that spans both areas.
