Question

I really prefer pages with full width (I believe most people do), is there any way to permanently set it by default?

Comments

This for Desktop app would be great.

Answer 1

I believe so via some CSS. In Stylish, I added:

.notion-page-content {
    width: 100% !important;
}
.notion-scroller > div > div {
    width: 100% !important;
}

If you're using Notion on browser, you can install Notion-Boost extension to add extra tweaks like full width and small text for all pages by default.

Answer 3

You can't natively. Only one by one at the moment, but hopefully Notion adds this option in the future.
