Is the medium size big enough for a standard loaf?

A regular sliced loaf fits, but long artisan loaves and tall round loaves can be a squeeze. Measure your usual loaf against the interior before buying.

Does the roll lid need clearance above it?

No. The lid rolls back into the box, so you can slide it under a shelf or cabinet. That is its main advantage over a hinged-lid box.

Can I stack things on top?

Yes. The flat top is designed to hold Brabantia storage canisters or small jars, which adds usable space without taking more worktop.

Will it keep crusty bread fresh?

It keeps bread at room temperature and out of the air, but the steel body has no ventilation, so very crusty bread may soften over a few days.

Wipe the matte steel with a damp cloth and dry it. Avoid abrasive cleaners, which can dull the finish.

Is it better than a plastic bread bin?

It looks better and the roll lid saves space, but plastic bins often cost less and come in larger sizes. Choose this for looks and footprint, not capacity.
