If your topper base does not extend past the thinning area by about 2.5 cm on each side, it is probably too small. For crown thinning, I’d keep it simple: measure the thin area, add 2.5 cm to the width and length, then choose the base that lets the clips sit on stronger hair.
Here’s the short version:
- Small crown area: a small-base topper can work if the clips still sit outside the thin patch.
- Mid-sized crown thinning: a large-base topper usually blends better and sits flatter.
- Large sparse crown area: a 23 × 23 cm (9 × 9 in) base is often the safer pick.
- If you’re between sizes: I’d go up a size.
A quick example: if the thinning patch measures 10 × 10 cm, I’d look for at least 12.5 × 12.5 cm of base coverage. That extra space helps stop clips from grabbing weak hair, which can lead to slipping, lifting, or a tight feel.
What matters most is not just hiding the centre. Crown thinning often spreads in a round shape, so the edge coverage matters just as much as the middle. That’s why a base that looks slightly bigger on paper can look softer once it’s on.
| Crown thinning area | What I’d look for | Likely fit |
|---|---|---|
| Up to 8 × 13 cm | Light coverage and root help | Small-base topper |
| About 13 × 13 cm to 17 × 17 cm | More edge coverage and safer clip placement | Large-base topper |
| 23 × 23 cm or more | Coverage across most of the crown | Large-base topper |
My rule of thumb: if the base edge lands inside the thinning zone, it’s too small.
Below, I’d walk through how to measure the area, how to judge your coverage level, and how to spot a topper that won’t sit right before you buy.
Hair Topper Base Size Guide for Crown Thinning
Measure the thinning area before choosing a base size
Start by measuring the thinning area with a flexible tape. You need two numbers: the width of the thinning area and the front-to-back length. Measure into the denser hair where the clips will sit, not right at the sparse edge.
How to measure crown thinning in centimetres
Stand in front of a mirror in good light, or ask someone to help. Find the widest visible part of the thinning area and measure straight across. Then measure from the point where the thinning starts at the front to where it stops toward the back. Write both numbers down in centimetres.
Next, add 2.5 cm to both measurements so the clips sit on healthy hair [2]. For example, if your thinning area is 10 cm wide by 10 cm long, you’ll want a base that covers at least 12.5 cm by 12.5 cm. If the topper edge sits inside the thinning zone, it’s less secure and tends to be more visible.
Use those adjusted measurements to work out whether your crown thinning falls into a mild, moderate, or advanced coverage range.
Thinning level guide: mild, moderate and advanced crown thinning
| Thinning Level | Approx. thinning span (cm) | Best Silkara fit and result |
|---|---|---|
| Mild | Small patches or widened part up to 8 × 13 cm | Small-base Silk Topper - subtle volume and root coverage with a clip in hair topper with bangs |
| Moderate | Noticeable diffused thinning across the crown, 13 × 13 cm to 17 × 17 cm | Large Silk Base Topper - wider edge coverage blends more softly across a broader thinning area |
| Advanced | Extensive sparse areas or larger bald patches, 23 × 23 cm or more | Large Silk Base Topper - full crown restoration; greater edge coverage means a softer, more natural blend |
This guide helps you judge whether a small-base or large-base Silkara topper will sit flatter and blend better.
If your measurements fall between sizes, go with the larger base so the clips can grip healthy hair.

Choosing the right topper size for your level of crown thinning
Crown thinning needs coverage across the full area, not just the spot in the middle. The key is to match the base to the whole thinning section so the topper sits flat and the clips fasten into stronger hair. From there, use your measurements to pick the smallest base that still reaches beyond the thinner area.
Mild thinning: when a small-base Silkara Hair topper is enough
For smaller areas of crown thinning, a small-base Silkara Hair topper can blend in neatly without adding extra bulk.
Moderate thinning: why a large-base Silkara Hair topper blends better
When thinning starts to spread across more of the crown, a large-base Silkara Hair topper gives better coverage and a softer blend. It also makes clip placement easier, because you can secure them into stronger hair outside the most fragile section instead of clipping into thinner areas that may not hold the piece well [1][2].
Advanced thinning: why a larger base looks more natural
With more advanced crown thinning, a larger base covers the full thinning area instead of sitting over the centre alone. Silkara Hair's 23 x 23 cm (9 x 9 in) silk base covers more of the crown, which lets the clips sit in stronger hair around the edge of the crown [1][2].
If your crown thinning is wide, move up to the larger base for a softer, more natural finish.
If the base still feels close to the thinning zone, check the signs it is too small before you buy.
How to avoid buying a topper that is too small
Once you know your crown measurements, check one more thing: does the base extend past the thinning area? If it stops inside that area, the clips may not have enough strong hair to hold onto.
Signs your topper base is too small for your crown
The clearest sign is simple. The clips sit on sparse hair instead of healthier hair around the outer edge. When that happens, they can’t support the topper’s weight well, and the piece may shift, lift, or feel tight while you wear it [2]. If there isn’t enough hair around the perimeter to secure the clips, you likely need a bigger size [2].
That perimeter fit matters most. If the clips don’t have a solid anchor point, the base is too small.
A base that’s too small can also change how natural the topper looks.
Why more coverage can look softer and more natural
When crown thinning covers a broad area, a small base can pile extra density into one spot. That sharp contrast can make the thinning stand out more.
A larger base spreads volume over a broader area, so the shift between the topper and your own hair looks more gradual [1].
"The large base design provides wider coverage and blends naturally with your own hair. It adds instant fullness and helps create a balanced, voluminous look."
- Silkara Hair [1]
That extra coverage can help the topper blend in with less effort.
Conclusion: Match your base size to the width of your crown thinning
Once you have your measurements, compare them with the nearest Silkara base size. Measure the visible thinning area from front to back and from side to side. Then add 2.5 cm to both numbers so the clips attach to healthy hair outside the thinning area [2].
If your thinning is quite small and the hair around the edges is still strong, the small-base Silkara Hair topper should do the job. If the thinning covers more of the crown, the Silkara Large 9 × 9 inch Silk Base Topper is a better fit because it gives you more coverage and helps with clip placement [1]. As the thinning spreads across a broader part of the crown, it makes sense to go up a size for better coverage and a more secure hold.
If the base would end inside the thinning area, go with the larger size. A base that falls short can leave the edges exposed, which makes thinning stand out more [1].
If you're stuck between two sizes, choose the larger one. When in doubt, size up.
FAQs
How do I measure an uneven crown thinning area?
Use a hand mirror and a wall mirror in good lighting to see exactly where your hair density starts and stops. Once you’ve mapped the full area, measure the length from front to back and the width at the widest point.
Write down both measurements in centimetres. Then add 1.5 cm to 2.5 cm to each measurement so the clips can grip securely to strong, healthy hair.
Will a larger topper feel bulky or hot?
Not if it’s fitted the right way for your thinning area. A topper that’s too large can feel bulky and tougher to blend, but Silkara toppers are made to feel lightweight and breathable for all-day wear.
The key is getting the size right. Add 1.5 cm to 2.5 cm to your measurements so the topper sits flat and stays secure. The right density matters too, because it helps the topper feel natural and comfortable instead of heavy.
Can I wear a topper if my hair is very fine?
Yes. A topper can work well even if your natural hair is very fine, as long as there’s enough healthy, denser hair around the thinning area for the clips to hold onto and for the edges to blend in.
Measure the thinning area, then add 1–2 cm. That gives the clips a place to sit on stronger hair instead of sparse sections. If the thinning covers a broader area, a larger base can look more natural. Just don’t go for a topper that’s too thick or bulky, because that can look out of place on fine hair.
