Hi Peili,

We discussed this feature request with our UX team. Our state is that the icons won't change their size. The main reason for this decision is the relationship between icons and font. The size of the icon stays the same as the size of the font (text), to keep a consistent look in places where they are used together.

Having this in mind, I am changing the status of this request to Declined. In the main section of the post, I will add a link to a knowledge base article on how to make Compact Grid elements smaller. As an alternative to the feature, the article shows the possible custom approach to reduce the size of the icons and the font.

Hello Peili,

Albeit the current markup is by design, I have forwarded this question to our UX team who will re-check the most optimal output given the configuration.

In the meantime, please consider overriding the size of the icons through a custom style, similar to:

<style>
    .k-table-th .k-svg-i-filter {
        width: 14px;
        height: 14px;
    }
</style>

Here is a the demo snippet with the above style: https://blazorrepl.telerik.com/ceOTYgap14jCjkK431

Lastly, note this only covers the filter icon. For including additional icons, the selector should be changed.
