Locs Size Available
Before settling down on the size of locs, you should first know about the variety of loc size categories. Here are the main loc sizes.
The traditional locs differ in size from large locs to small locs.
- Large Locs
This diameter is about the same size as a sharpie marker. They are thick and appear fancy. Many locs in this category are free-form with significant volumes.
- Medium Locs
The medium-sized locs have a thickness of about a #2 pencil. You will notice this size on many people who wear locs.
- Small Locs
Small locs are also a standard loc size noticed by many people. This size is almost the same as a chopstick.
Microlocks are generally tiny. They look smaller than traditional locs but larger than sisterlocks. In addition, their thickness resembles that of a drinking straw.
Sisterlocks are the thinnest locs among all of them. The smallest sisterlocks are yarn-sized, with parts varying from 4/8 to 3/8 of an inch.
How to Determine Your Locs Size and Number
The locs are usually compact and grow thinner during maturity. You will notice that what you start with is not what you end up with. Here is an approximate idea of how many locs sizes and numbers you require for each category.
Large Locs (<50 Locs)
Achieving large traditional locs requires you to create between 20 – 50 locs. Keep in mind that if you have fewer locs, locs will get thicker when they mature.
Therefore, if you aim for very thick locs, you could choose 20 locs. However, if you want thinner locs, you could go for 50 locs.
You should not do less than 20 locs. This is because locs will get extremely thick. The thicker the locks are, the more water they retain. At this point, it will be hard to let the hair to air dry when washed.
Moreover, consistent buildup and residue on large locs can lead to mold growth.
Medium Locs (51-100)
When going for medium locs, create anything from 51-100 locs. However, if you have thin hair and wish to have pencil-sized locs, you should choose 51 locs. But if you got thicker hair, you should get 100 locs or anything close to 100.
Medium locs give you a full head with good volume. Maintenance and styling are pretty easy due to the lower number of locs.
Small Locs (101-200)
Small locs require you to have between 101-200 locs. Like large and medium-sized locs, create 200 locs or anything close to that when you have thicker hair. While for thinner hair, go for around 101 locs.
101 locs will create medium-thin dreads, while 200 locs will give you thin locs. Generally, these depend on how thick and coarse your hair is.
Microlocs are very thin and require between 201-250 locs. If you want your Microlocs size to be really thin, create about 250 locs.
If you want to get locs but want more styling options and flexibility, then Microlocs could be your ideal choice.
You can do these locs on your own and style them to your liking. The good thing about Microlocs is that you can create medium locs or large locs. They also do not need a lot of maintenance.
Sisterlocks (>250 Locs)
Sisterlocks are extremely thin and are more than 250 dreads. Instead of the twisting or rolling technique, these locs are professionally locked by a patented tool. 
Sisterlocs are uniform, with perfect parts made by a specific grid. You can choose sisterlocks if you are looking for versatility in styles done on non-loc hair.
They are three sizes; small, medium, and large sisterlocks. Achieving these locs may be challenging as a lot of time is taken during the process. Re-twisting will also take you hours; however, the results are marvelous.
How to Choose Perfect Locs Size for You
When choosing your loc size, you need to consider several factors. You should select the right size to protect your hair from damage and popping off. Here are some tips.
The locs you start with are not what it turns out to be. Locs might be bigger initially, but as the locs mature, they compact and get smaller. So it is better to start bigger than what you expect.
Have a Loc Model
It is better to have a loc model whose hair you like. The hair texture should be similar to yours. But have in mind that it might not turn that exact way due to factors like hair texture and density.
Get More Parts
For less hair volume, it is advisable to get more parts. This way, your hair will look fuller. Otherwise, if you have less hair and get fuller parts, your hair will look skimpy.
Avoid Bald Looking
If you have thin and go for big locs, your head will look bald. It will look like there is less hair.
Locs Frame Reference
The parting size gives you a reference of what locs size you should expect when your locs mature. Locs tend to end up with a thickness close to the size of the parting.
Small Locs to Start
Once you get your locs and do not like the size initially, you can take them down or combine them. But for too large locs, you can not separate them into smaller parts. So it is preferable to get small-sized locs.
When you begin with smaller locs, they will be even smaller when mature. The more your locks grow and get longer, the more they compact.
Consider looking into the overall cost of your locs. It is best if you keep up with the cost of professional maintenance. With larger locs, the maintenance costs are low, while smaller locs are costly.
Locs are low maintenance compared to other hairstyles. However, you will set a time commitment every time you go for professional care.

FAQs about Dreadlock Sizes & Numbers
How many locs make a full head?
For an adult head, the average number of locs ranges from 40-110, depending on their sizes. Your hair density and the preferred loc size will determine the bundles you need.
What is the difference between sisterlocks and Microlocs?
They differ in the installation technique, size, and cost.
Sisterlocks’ size is smaller than Microlocs. It is created by making parts on the hair in a defined grid pattern and then locked by a unique interlocking tool. Installation of sisterlocks is done by registered Sisterlock consultants. 
While Microlocs are started as braid, twist, or coil, which is hand-rolled and locked using waxes or gel. Microlocs can be created without formal training. Installing Microlocs is less costly than installing sisterlocks.
Do dreads get thicker or thinner over time?
Dreads get thicker and thinner while undergoing the different loc stages to maturity. The thickness will vary over time as they lengthen significantly during the first two years when the hair matures. But when mature, they should look a little thicker on healthy hair.
What’s the best size locs for fine hair?
A reasonable amount of locs for fine hair would be around 51 locs. If you have thicker hair, go for about 100 locs. With small traditional locs, you should get 101-150 locs.
