Why should you use capital letters in hashtags?

1: Accessibility

Proper capitalisation improves accessibility for people with visual impairments who may use screen readers. Screen readers often pronounce capitalised words separately, making the content more understandable. – it’s the right thing to do and will help your campaigns reach more people.

2: Readability

Hashtags are often used to convey a specific message or theme. Capitalising the first letter of each word makes it easier for users to read and understand the hashtag’s meaning. Proper capitalisation makes longer hashtags easier to decipher, especially if they contain multiple words. For example: #thisisalonghashtagthatisdifficulttoread #ThisIsALongHashtagThatIsEasierToRead

3: Clarity

Capitalisation helps distinguish between individual words within a multi-word hashtag. Words can blend together without capitalisation, potentially changing the intended message or making it harder to interpret.

4: Branding & Aesthetics

Capitalising the first letter of each word in a hashtag can make it visually appealing and help it stand out. This is especially relevant when users are trying to promote a specific brand like Coca-Cola’s #ShareACoke campaign or a cause such as Always’ #LikeAGirl, where they took the term “like a girl” away from suggesting weakness by showing young girls who were uninfluenced by society’s expectations, turning it into a hashtag of strength.

5: Consistency

Following a consistent capitalisation style in hashtags makes it easier for others to adopt and use the same format. This can lead to higher visibility and engagement for the hashtag. For example, #bigcheeseweekender vs. #BigCheeseWeekender

6: Searchability

While capitalisation doesn’t affect the functionality of a hashtag (as they are not case-sensitive on most social media platforms), it can make the hashtag more readable and memorable, indirectly impacting its searchability and discoverability.

7: Context

Including capitalisation in hashtags makes incorporating them into sentences easier, maintaining context (#AsOpposedTo including them as footnotes in tweets and posts) – especially when it consists of multiple words.

On the other hand…

OK, there’s a caveat that using lowercase letters where the #hashtag is a single word makes it look more like a conventional sentence fragment or commentary within the text. But #single word #hashtags, more often than not, cover too broad a topic.

Professional tip

Use your SEO Keywords as hashtags

Struggling to decide on a hashtag? Try your SEO keywords! Check what other users are posting under those keywords. If the content is mostly related to your post and the hashtag is frequently used, then it’s a good choice.

What if I don’t use capital letters in hashtags?

Not convinced? Check out these infamous examples of hashtag bloopers that could have been avoided by capitalising the first letter of each word.


This hashtag was famously misinterpreted due to the lack of proper capitalisation and spacing. #susanalbumparty It was intended to promote Susan Boyle’s album release party (#SusanAlbumParty), but the lack of spacing between “Susan” and “Album” led to a humorous and unintended interpretation.


Another famous one, #nowthatchersdead: This hashtag emerged after the passing of former British Prime Minister Margaret Thatcher. A good (or bad) example of how combining words without using capital letters in hashtags in place of spacing (#NowThatChersDead) led to confusion and unintended interpretations (some readers read it as “Now that Cher’s dead”).

Hashtag FAQs

Do capital letters in hashtags matter?

Yes and no! In functional terms, hashtags are generally not case-sensitive, meaning capitalisation does not affect how the hashtag works or how it’s used for searching on platforms like Twitter (X), Instagram or Facebook. That said, adhering to the convention of capitalising the first letter of each word can contribute to the overall effectiveness of the hashtag in conveying its intended message and encouraging engagement.

Can you use numbers in hashtags?

Yes, but make sure that you include letters. If you write #1 or #123, the hashtag will not be hyperlinked and is therefore not searchable. However, the hashtag will work correctly if you include letters following the numbers in the hashtag, for example, #123go.

Why #AccessibilityMatters on social media?

At least 20% of the population is estimated to have a long-term illness, impairment, or disability. Many more people experience temporary or situational health conditions that affect their ability to comprehend information due to cognitive impairments or sight or hearing difficulties. Inaccessible social media campaigns risk alienating audiences, reducing impact and breaching key legislation in Public Sector organisations.
