What size are these knobs?

Each knob is about 1.26 inches wide and 0.87 inches tall. That is a small knob, closer to a dresser pull than a large kitchen cabinet knob.

The listing does not state that mounting screws are included. Check the pack contents before buying, or plan to reuse the screws from your old knobs.

Will they fit standard cabinet holes?

Most cabinet knobs use a single screw through one hole, so these should fit standard drilled fronts. Confirm the screw length matches your door thickness.

How many packs do I need for a kitchen?

Each pack has four knobs. Count your doors and drawers and divide by four, then add a pack for spares.

Is aluminum a good material for cabinet knobs?

Yes for moisture resistance, since aluminum does not rust like steel. It is softer, though, so it can dent or scratch with hard knocks.

When is the best time to buy?

At $8.49 at Lowe's as of November 7, 2026, the price is already low. Small hardware like this rarely drops much further, so waiting is unlikely to save much.
