What length hair extensions should I choose?

If you are new to hair extensions, you may be a little unsure as to what length to for, and with 4 different lengths to choose from, it can be a very difficult decision.

Before jumping in and selecting a length at random or based on price, it is first worth considering a few points to be sure you are making the right choice.

lengthWhere will they sit on my body?

When thinking about the length you wish to go for, often you think about this in terms of where the hair will sit against your body e.g ‘I want the hair to come down to my bra line’.  As a rule of thumb, the picture to the right is a rough estimate for where on your back your hair extensions will reach, however as you will see from the additional tips below this is only an estimate, and not a one size fits all guide.


Your own height will play a big factor in your decision about the length of your hair extensions.  When selecting a length, what many individuals forget is how your height will impact the overall look of your hair extensions.  For example if you take 2 girls, one who is 5 foot 8 inches tall and the other is 4 foot 8 inches tall, and they both purchase 16” hair extensions, due to the height differences the 4 foot 8 inch girl will appear to have much longer hair extensions due to where they sit on her body in comparison to the taller girl, even though they have purchased the same length.


Another factor to consider is the way you plan to have the hair styled after fitting.  Once fitted you may only wish to have a small amount trimmed from the bottom to tidy up and finish of your look, however if you are considering removing slightly more, or opting for a layered and tapered look, going for a slightly longer length than your finished look may be a better option.  For example, if you are looking for long and thick extensions with a little styling e.g. layering etc, you may benefit from purchasing 20” hair extensions with it in mind to trim them to 18” to achieve your finished look.


If you are in between 2 lengths, it is usually recommended that you purchase the longer of the two.  If you are between 16” and 18” for example, a full head of 16” hair extensions will cost approx. £108.00 to purchase, and 18” will be £124.00, a £16.00 difference.  If you are undecided and opt for the longer length, although costing slightly more, you can always have them cut and trimmed if the length is a little longer than you expected, and it would have cost you an additional £16.00.  If you opt for the 16” and find they are too short however, you would have spent £108.00 on extensions you aren’t quite happy with.  Purchasing the longer length protects you again disappointment in the event you are unsure of the finished look.

Curls & Waves

When your hair extensions arrive and are first fitted, they will be beautiful and straight, however if you prefer to wear your hair with a curl or a wave, this will reduce the appearance of the length as the extensions bounce up to accommodate the wave.  If you plan on wearing your hair like this regularly, and like the look of 20” hair extensions, you may wish to consider opting for 22” to ensure that when you apply the curl your hair extensions still have the appearance of 20” length.

Future trimming

Finally, when choosing a length you will want to consider any future trimming or styling you have in mind.  If you like to mix up your hair style regularly, you may wish to opt for a longer length so that once the extensions are fitted, as the months pass you have the ability to cut and trim your hair into different styles, getting shorter as you go but still having lengthy hair extensions.  The longer your hair extensions are, the more styling opportunities you will find.

Now you have a better understanding of what you will need to take into consideration when choosing your hair extension length, you should be able to choose a length that is suited to your needs to ensure your hair extensions look exactly as you planned them to, avoiding any unnecessary disappointments.
