Why TikTok formats are so important

TikTok is growing rapidly, which is why the still young platform is becoming increasingly relevant for companies and brands. Recently, companies and brands have been competing for the most attention and visibility among their target groups (customers, staff).

However, the content will only perform well if the correct TikTok dimensions are adhered to. It is therefore important to get the presentation right so as not to compromise on reach and engagement. That is why we are expanding our social media guide to include the correct TikTok dimensions.

Vertical videos are crucial

The standard format on TikTok is 9:16 (1080 x 1920 px). To avoid incorrect display and black bars, for example, the correct TikTok resolution is very important. In addition, the portrait format is best suited for maximising visibility in the app.

The good thing is that the TikTok video format does not differ from other social media platforms. So if you produce content for the TikTok channel, it makes sense to also publish the video directly as an Instagram Reel and YouTube Short.

There are also posts with photos

TikTok is known for the viral short videos created by creators and companies. These formats are sure to generate the widest reach. However, TikTok also offers normal posts and carousels with photos.

There is still relatively a lot of movement in these formats, and deviating aspect ratios are not too bad. However, the classic formats are still suitable for providing existing followers with a comprehensive channel. This is especially true for target groups who obtain their information and first impressions from the platform.

Do not underestimate the caption

It's not just the right formats that are important. You also need to consider the right TikTok caption length or maximum text length. TikTok limits captions to 2.200 characters. However, there are experiments underway to increase this limit.

However, captions are becoming increasingly important, similar to Instagram, while hashtags are becoming less relevant. However, please note that they are not yet completely irrelevant and assist both users and the algorithm in classifying and finding your content.

In order to always be able to display the latest TikTok stars and be active on multiple social media channels at once, it makes sense to use a social media tool. These tools take such requirements into account and also check for limitations such as caption length.

This is important for thumbnails

Thumbnails are not as relevant on TikTok as they are on Instagram. The majority of video views come from the legendary algorithm, which plays the video before a thumbnail can even be displayed.

Nevertheless, its importance should not be overlooked. Channel design is particularly relevant for (younger) target groups who use TikTok to form impressions of companies and brands. This is precisely where thumbnails come into play, as they have a significant influence on the overall impression of the channel. So it's no surprise that the 9:16 format should also be used here for the correct TikTok thumbnail size.
