Why Do Clip-In Wefts
Come in Different Sizes?

If you are new to clip-in hair extensions, a full set can look surprisingly complicated at first. Why are some wefts wide and others small? Why are two 4-clip wefts not exactly the same width? And how many clips should a complete set have? Here is the thinking behind the current UNILOVELY 8-weft, 20-clip Seamless Clip-In set.

“A well-designed Clip-In set is not about making every weft identical — it is about giving different areas of the head the right balance of coverage and placement flexibility.”

The Quick Answer

8 wefts.
20 clips.
Different widths.

Our current UNILOVELY Seamless Clip-In Extensions are designed as an 8-weft set with 20 clips total.

The wefts are intentionally made in different widths because the human head is not equally wide from one placement area to another. A large back section can accommodate a wider weft, while higher or more lateral areas often benefit from narrower pieces.

Instead of forcing one width to work everywhere, a combination of 4-clip, 3-clip, 2-clip, and 1-clip pieces gives you more ways to distribute the hair around your own head shape.

What Is Included?

The UNILOVELY 8-weft, 20-clip configuration.

1 × 4-clip
Wide back weft. The widest piece is designed to provide broad coverage through a larger back section of the head.
1 × 4-clip
Slightly narrower 4-clip weft. It keeps four attachment points while fitting a row where slightly less horizontal width may be available.
2 × 3-clip
Medium-wide wefts. These provide another level of coverage without requiring the width of the two largest pieces.
2 × 2-clip
Medium wefts. Their shorter width makes them useful when you want more localized volume and greater placement flexibility.
2 × 1-clip
Small side wefts. These compact pieces allow targeted placement around smaller areas, including the sides and front sections when appropriate for your hairstyle.
Important: Placement is not a rigid map. Head shape, natural density, haircut, desired volume, and styling can all change where each weft works best. The configuration gives you options rather than forcing every wearer to use exactly the same placement pattern.

A Common Question

Why are the two 4-clip wefts different widths?

This is one of the details that can look unusual if you are buying Clip-In extensions for the first time.

Both pieces have four clips, but that does not mean they need to have exactly the same width. The number of clips and the width of the weft solve two related but different problems.

The clips provide attachment points. The width determines how much horizontal area the piece is designed to cover.

Because the available width around the head changes as you move between placement rows, using one wider 4-clip piece and one slightly narrower 4-clip piece can create a more adaptable set than simply duplicating the same large weft twice.

The wider 4-clip weft

Gives broad coverage where there is more horizontal space, making it useful as one of the main foundation pieces through the back.

The narrower 4-clip weft

Keeps four attachment points but reduces overall width, giving you another option for a placement row where the head naturally becomes narrower or where a full-width piece would be unnecessary.

Why Multiple Weft Sizes?

Why not make every Clip-In weft the same size?

Reason 01

Your Head Changes Width

The available horizontal space is different at the back, higher sections, and sides of the head. Different widths can follow those changing proportions more naturally.

Reason 02

Volume Is Not Needed Equally

Some areas may need broad coverage while others only need a smaller amount of hair. Multiple weft sizes allow more targeted distribution.

Reason 03

Placement Stays Flexible

A set made only from very wide wefts would offer fewer ways to adjust placement around different head shapes, haircuts, and styling goals.

Different Pieces, Different Jobs

How each weft size contributes to the set.

4-Clip Wefts

Main Coverage

The two largest pieces create much of the broad coverage through the back, with two widths to suit different placement rows.

3-Clip Wefts

Flexible Coverage

Medium-wide pieces help continue volume without requiring another full-width back weft.

2-Clip Wefts

Localized Volume

Shorter pieces can be positioned where you want additional fullness but do not need a large amount of horizontal coverage.

1-Clip Wefts

Targeted Placement

The smallest pieces provide extra control around smaller side or front areas and can help fine-tune the finished blend.

An Important Distinction

More clips do not automatically mean better Clip-In extensions.

Clip count is only one part of the design. What matters is how the clips are distributed across the wefts, how the weft widths work together, how much hair the set contains, how flat the base sits, and the quality of the hair itself.

Why 20 Clips?

Distribution matters more than chasing a number.

It can be tempting to compare Clip-In sets only by asking which one has the most clips. But a larger number is not automatically a sign of better design.

In our current set, the 20 clips are distributed across eight differently sized wefts. That gives the larger pieces multiple attachment points while still preserving smaller, more flexible pieces for areas where a wide weft is not necessary.

The goal is not simply to add clips. It is to create a complete system in which broad coverage and precise placement can work together.

That same product-detail approach is part of how we think about our broader Remy Human Hair Extensions : the usefulness of a feature matters more than the feature count alone.

For First-Time Clip-In Wearers

A simple way to understand where the pieces go.

1. Think broadest first

The widest 4-clip piece is generally one of the main back wefts, where you have more horizontal space and want broad coverage.

2. Use the narrower 4-clip piece for the next level of coverage

As the available width changes, the slightly narrower 4-clip weft gives you another large piece without simply duplicating the widest shape.

3. Use 3-clip and 2-clip pieces to distribute volume

The medium pieces allow you to build fullness around the hairstyle without stacking only large wefts in one area.

4. Use the 1-clip pieces for smaller areas

The two smallest pieces give you targeted control around the sides or front where a wider weft may be unnecessary.

These are general placement principles rather than mandatory instructions. Your best placement can change with your head shape, natural hair, haircut, chosen extension weight, and desired style.

Do You Have to Wear All 8 Wefts Every Time?

No. A complete set gives you options, but that does not mean every styling situation requires every piece.

If you want a fuller transformation, you may choose to use more of the set. If you only want a lighter amount of volume for a particular hairstyle, fewer pieces may be enough.

This flexibility is one of the reasons multiple weft sizes are useful: instead of treating the set as one fixed unit, you can adapt the placement to your own hair and the look you want that day.

Choosing Clip-In Extensions

Look beyond the number of clips.

Consider 01

Weft Construction

Look at how the pieces are distributed and whether the widths give you enough flexibility for your own head shape and styling needs.

Consider 02

Hair Quality

The clips hold the extension in place, but the hair itself determines much of the finished look, movement, feel, and styling experience.

Consider 03

Length, Weight & Color

A well-designed structure still needs the right length, amount of hair, and shade to blend naturally with your own hair.

Structure Helps. Color Matching Completes the Blend.

Having the right weft configuration gives you placement flexibility, but a natural-looking result also depends heavily on choosing a shade that works with your own hair.

Look at your hair in natural light and pay attention not only to the darkest or lightest strand, but to the overall color through the lengths where the extensions will blend.

Frequently Asked Questions

Clip-In Wefts & Clips FAQ

How many wefts are in UNILOVELY Seamless Clip-In Extensions?

The current UNILOVELY Seamless Clip-In set is designed with 8 wefts total: one wide 4-clip weft, one slightly narrower 4-clip weft, two 3-clip wefts, two 2-clip wefts, and two 1-clip wefts.

How many clips are in the complete UNILOVELY Clip-In set?

The eight wefts contain 20 clips total. The clips are distributed across different weft widths rather than placing the same number of clips on every piece.

Why are the two 4-clip wefts different widths?

The human head offers different amounts of horizontal space at different placement rows. One wider 4-clip piece provides broad back coverage, while the slightly narrower 4-clip piece keeps four attachment points but gives you a different width for another placement area.

Why do Clip-In hair extensions use different weft sizes?

Different weft sizes make it possible to distribute hair across broad and narrow areas of the head. Larger pieces provide more coverage, while smaller pieces offer more precise placement around areas where a full-width weft is unnecessary.

Are more clips always better in Clip-In extensions?

No. Clip count alone does not determine quality. Weft distribution, width, hair weight, base construction, hair quality, and how well the set suits the wearer are also important. The goal should be balanced construction, not simply the highest clip count.

Do I need to wear all 8 Clip-In wefts every time?

Not necessarily. A complete set gives you placement and volume options. You may use more pieces for a fuller result or fewer pieces when you want lighter volume. The best setup depends on your natural hair and hairstyle.

Where should the 1-clip wefts be placed?

The small 1-clip pieces are intended for targeted placement in smaller areas, often around the sides or front where appropriate. Exact placement should be adjusted to your own haircut, density, head shape, and desired blend.

Are UNILOVELY Seamless Clip-In Extensions real human hair?

Yes. UNILOVELY Seamless Clip-In Extensions are made with 100% Remy human hair. You can explore the full Remy Human Hair Extensions collection for more options.
