This is a sample design essay, not an account of a real room.
The room before the furniture
Before the chair arrived, the room was already doing something. Morning light crossed the floor. The window made a frame for the tree outside. The bare wall gave the eye somewhere to rest.
Then came a table, a lamp, three pictures, and a shelf. Each was pleasant on its own. Together, they made it harder to see the tree.
So the shelf went elsewhere.
Space is part of the composition
A page has a similar problem. Every label, rule, badge, and box asks for a little attention. Add enough of them and the story has to raise its voice to be heard.
Space does not need to be filled to be useful. It separates ideas, makes a title feel like a beginning, and helps a short paragraph carry a little more weight.
Sometimes the most helpful part of a design is the part you decide to leave alone.
That does not mean every page should be sparse. A directory needs information close together; an essay can afford a slower pace. The space should suit the reading.
Try one small subtraction
Look at a page you know well and ask what could leave without taking meaning with it. An extra border? A repeated label? A sentence that says what the title already said?
Remove one thing. Read the page again.
In the imagined room, the chair stayed beside the window. The light still crossed the floor. With the shelf gone, there was finally enough room to notice both.
