How to keep achillea millefolium 'cerise queen' smaller

You are not stuck with the maximum size. For achillea millefolium 'cerise queen' specifically, these are the levers, in order of impact:

Remove runners, plantlets or offsets as they appear if you want it to stay a single tight clump.
Keep it slightly pot-bound; a snug pot naturally limits how wide the clump can get.

The keep-it-smaller method, step by step

Lift the whole plant. Slide achillea millefolium 'cerise queen' out of its pot in spring when the clump has filled it.
Split the clump. Tease or cut the rootball into two or more sections, each with healthy roots and growth.
Repot one division. Put a single division back in the original pot to reset it to a smaller size; pot or give away the rest.
Remove offsets as they form. Through the year, detach new runners or pups to stop it spreading again.

Give it a wider pot and let the clump fill it — width is exactly how this plant gets bigger.
Good light plus regular feeding maximises offset and runner production.
Leave plantlets and offsets attached and feed through the growing season for the fastest spread.

Light is almost always the ceiling. The achillea millefolium 'cerise queen' light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When achillea millefolium 'cerise queen' outgrows the room (or the pot)
