Market size represents the total number of potential viewers who might be interested in a topic or channel. It’s important to consider the market size as it plays a role in the potential success of a YouTube channel.

Market size is also important for a channel's scalability. Scalability in this context refers to a YouTube channel's capacity to grow and manage increased views without compromising quality or productivity. If the market is too small, it can be challenging to grow and monetize the channel sufficiently. Targeting a larger market increases the pool of viewers who might be interested in the content, leading to a more scalable channel growth.

For example a gaming channel covering an old game with little interest are likely to be limited by it’s market size: there’s not enough people interested in the topic for the channel to consistently grow.

Creators can expand their reach by creating content that is relevant to larger markets. Different ways to increase market size includes:

• Broaden the topic: make small adjustments to the topic to make it more applicable to more people

• Cover Multiple Markets: Create content relevant to different interests simultaneously. Be vary of the potential drawbacks of this to your channel offering.

If your channel itself can’t scale, you have a problem. However, if your channel can scale, but your videos can’t, you need to think differently to target larger markets.
