How many bundles do I need for a full wig?

When it comes to wigs, one of the most common questions is “How many bundles do I need for a full wig?” The number of bundles needed can vary depending on several factors like hair type, head size, and desired fullness. In this comprehensive guide, we will walk you through everything you need to know to determine the ideal number of bundles for your full lace or frontal wig.

What are hair bundles?

Hair bundles, also sometimes called wefts or tracks, are sections of hair that are sewn together into a long piece. Each bundle contains a certain weight of hair, usually ranging from 50 grams up to over 200 grams. Bundles are used to create volume and length when making wigs and hair extensions.

When shopping for bundles, you’ll notice they come in different lengths, typically ranging from 12″ to 30″. The length you choose will depend on your desired wig length. For example, if you want a 16″ wig, you’d need 16″ bundles. The number of shorter bundles needed depends on the fullness you want to achieve.

Factors that determine how many bundles you need

There are a few key factors that determine how many bundles are required for a full lace or frontal wig:

Hair texture

The texture of the hair plays a big role. Thicker, kinkier hair types like African American hair require more bundles to create a full look. On the other hand, silky straight fine hair allows you to stretch bundles further with less fullness.

Head circumference

Your head size, and more specifically your head’s circumference, determines how much hair is needed to go all the way around. Someone with a petite head and narrow circumference may need fewer bundles than someone with a larger head circumference.


Longer styles require more bundles. The longer the look you want, the more bundles you’ll need to achieve it. A shoulder length style may only need 2-3 bundles, while a style down to your waist will need significantly more.

Desired density

How thick and full do you want your wig to look? The more density and volume you want, the more bundles you’ll need. If you like a flat, sleek look then you can get away with fewer bundles. But for voluminous curls and waves, additional bundles are a must.

How many bundles for different wig lengths

As a general guideline, here is how many bundles are needed for common wig lengths:

Short bob (10″ – 12″)

  • 2 – 3 bundles

Shoulder length (14″ – 16″)

  • 3 – 4 bundles

Bra strap length (18″ – 20″)

  • 4 – 5 bundles

Mid back length (22″ – 24″)

  • 5 – 7 bundles

Waist length (26″ – 30″)

  • 7+ bundles

Again, these ranges are general recommendations. Finer hair types can stretch bundles further than thicker textures. And your desired fullness will also require adjusting the number of bundles up or down.

How many bundles for head size

Head circumference also determines how much hair you need. Here are rough estimates for different head sizes:

Petite head (21″ – 22″ circumference)

  • 2 – 4 bundles for shoulder to mid-back lengths

Average head (22″ – 23″ circumference)

  • 3 – 5 bundles for shoulder to mid-back lengths

Large head (23″ – 24″ circumference)

  • 4 – 6 bundles for shoulder to mid-back lengths

Measure around your head above your ears and over the fullest part to find your circumference. Again, these ranges are simply estimates and your desired fullness and density will change the ideal number of bundles.

How to calculate bundles needed

If you want a more precise calculation, here is a simple formula:

  • Measure your head circumference in inches
  • Multiply it by the length of your desired wig in inches
  • Divide that number by the length of your bundles in inches

For example:

Your head circumference: 22 inches
Desired wig length: 16 inches

Bundle length: 16 inches

22 x 16 = 352 inches
352 divided by 16 = 22 bundles

So for a 16 inch wig on a 22 inch head, you would need around 22 bundles of 16 inch hair. Again you can adjust up or down based on your desired thickness and fullness.

Getting the right bundle lengths

When buying bundles for a full wig, you’ll want to get a range of lengths. Here are some tips:

  • Get your longest bundles in the length matching your desired wig length
  • Fill out the sides and back with mid-length bundles 2-6 inches shorter
  • Add in shorter bundles for the top and around the hairline for shaping and blending

For example, for an 18″ wig:

  • 12″ – 14″ bundles for the top and hairline
  • 16″ bundles for the back and sides
  • 18″ bundles for the length

Blending multiple bundle lengths creates a natural layered look.

Bundle weights

Bundles come in a range of weights, anywhere from 50 grams up to over 200 grams. Heavier bundles will of course give you more hair to work with.

Some typical bundle weights include:

  • 50 grams – more common for clip-ins
  • 100 grams – suitable for extensions
  • 125 grams
  • 150 grams

For a full lace wig, aim for 100 gram bundles as a minimum. But 150 gram bundles are ideal to give you the most hair to work with.

How many bundles for different densities

150% density

  • 5 – 8 bundles for shoulder to mid back lengths

180% density

  • 6 – 10 bundles for shoulder to mid back lengths

200% density

  • 8+ bundles for shoulder to mid back lengths

Density refers to how thick or full the hair looks. Most people prefer at least 150% density for a natural look. Go up to 180% – 200% density for extra volume and thickness.

Benefits of using multiple bundles

There are several benefits to using multiple shorter bundles rather than fewer extra long bundles for your wig:

  • More versatility – Allows creating layers and dimension
  • More affordability – Shorter bundles are cheaper than super long lengths
  • More natural appearance – Mimics natural gradual growth from short to long hairs
  • Less tangling – Shorter bundles tangle less than very long lengths

Should you buy extra bundles?

It’s a good idea to buy 1-2 extra bundles than the minimum amount you calculate. Reasons to get extras include:

  • Wig making can require more hair than expected
  • Gives you replacements in case of damage
  • Allows you to add length or fullness later on
  • Bundle lengths can vary slightly from company estimates

Just keep in mind excess bundles can go to waste if you don’t end up needing them. But 1-2 extras won’t hurt.

Pre-made wig bundles vs DIY

You have two options when it comes to obtaining bundles for your wig:

Pre-constructed wigs

Many brands sell ready made lace front and full lace wigs that come pre-bundled with a set number of bundles already sewn in. This takes the guesswork out of calculating how much hair you need.

DIY with loose bundles

Or you can purchase individual loose bundles and construct the wig yourself or have it made by a stylist. This gives you total control over how much hair goes into the wig. Just be prepared for the labor involved in making the wig.

Choosing hair bundle brands

When buying bundles, stick to reputable human hair brands known for quality. Some top options include:

  • Brazilian Virgin Hair
  • Peruvian Virgin Hair
  • Malaysian Virgin Hair
  • Indian Virgin Hair
  • Cambodian Virgin Hair
  • Mongolian Virgin Hair

Research reviews and ask for recommendations to select high quality hair that won’t tangle or shed excessively. Low quality bundles can quickly turn into a frustrating, expensive mistake.

Caring for your bundles and wig

Once you’ve constructed your fabulous full lace wig, be sure to care for it properly. Here are some tips:

  • Use a wig stand or mannequin head when storing
  • Avoid over brushing to limit shedding
  • Use a wide tooth comb and gentle, even strokes
  • Wash 1-2 times per month max to avoid drying out the hair
  • Use a sulfate-free wig shampoo and conditioner
  • Allow to fully air dry before styling to prevent damage
  • Use heat protectant spray before hot tools
  • Get regular trims to maintain the style


Determining how many bundles you need for a full wig requires factoring in your head size, desired length and density, and hair type. As a general rule of thumb, you’ll want 3-5 bundles for shoulder length wigs, and closer to 8+ bundles for waist length voluminous looks.

Blending shorter and longer bundle lengths, opting for thicker 100-150 gram bundles, and purchasing 1-2 extras will help you achieve a beautiful full lace wig with minimal frustration. And taking proper care of your human hair bundles will help your investment last.

Have fun rocking your luscious locks!
