How the Five Compare on the Numbers
Eight results came back and three are not cabinet knobs. One is a 12 inch electric cooktop with knob controls, which the search matched on the word knob. One is a set of 4 D shaft replacement knobs for air fryers and pressure cookers. The third is a genuine knob but a ceramic cloud shape sold for children’s rooms, and its own listing warns of a 1 to 3 millimeter variance because the measurements were taken by hand.
The five that remain publish the same specification in four different notations. Amerock and Ravinte both say 1-1/4 inches, Amerock adding 32 mm. Franklin Brass says 1-3/16 inches and 30 mm. Alzassbg says 1.46 inches and 37 mm. Cosmas says 1-1/8 inches. Converting those by hand is the first job of buying a knob, and no listing does it for you.
No usable weight comparison exists on this page, because the three published weights describe different numbers of objects: 0.1 pounds is one Amerock knob, 1.23 pounds is ten Alzassbg knobs and 2.6 pounds is thirty Ravinte knobs. Cosmas and Franklin Brass publish no weight at all, and Franklin Brass’s field figure was too small to be ten knobs so it was discarded. Nothing here can be ranked by mass.
The Three Figures That Decide a Knob
Diameter Is the One Everybody Publishes
Every listing gives a face diameter, and it is the figure that decides whether a knob looks right on a door. The range here is narrow, from 1-1/8 inches on the Cosmas to 1.46 on the Alzassbg, and the notations are inconsistent enough to hide that: 1-3/16 inches sits between 1-1/8 and 1-1/4 and reads like neither.
Two listings give a metric equivalent as well. Franklin Brass says 1-3/16 inches is 30 mm and Alzassbg says 1.46 inches is 37 mm. Amerock says 1-1/4 inches is 32 mm. Those conversions matter if you are matching existing hardware bought in either system, and Cosmas and Ravinte publish inches only.
Projection and Base, Published by Three
Projection is how far the knob stands off the door, which decides whether your fingers fit behind it and whether a drawer clears an adjacent wall. Cosmas publishes 1 inch, Alzassbg publishes 0.8 inches or 21 mm, and Ravinte publishes 7/8 of an inch under the label height. Amerock and Franklin Brass publish nothing.
Base diameter is the footprint that sits against the wood, and the same three publish it: Cosmas 5/8 of an inch, Ravinte 3/4, Alzassbg 0.6 inches or 15 mm. That figure matters when you are covering the mark left by old hardware, and the two listings that skip it are the two with the strongest finish claims.
Screws, and What Happens If They Are Wrong
Alzassbg Solves a Problem Nobody Else Mentions
Cabinet doors are not all the same thickness, so a knob screw that suits a 3/4 inch door is too long for a thin drawer front. Alzassbg supplies two sets of screws, 1 inch and breakaway, and tells you plainly that if you need them shorter you can cut the excess with pliers. That is the only listing here that addresses fitting rather than appearance.
Franklin Brass supplies ten 1 inch screws for ten knobs and says nothing about thickness. Cosmas supplies 1 inch screws polybagged with the knobs. Amerock says mounting hardware is included and never gives a length, and Ravinte does not mention screws anywhere in its bullets, which for a 30 pack is a notable omission.
What a 30 Pack Commits You To
Ravinte is the only pick sold in a quantity that does a whole kitchen in one order, 30 knobs, backed by a 365 day evaluation period. Amerock sits at the other end as a single knob with a limited lifetime warranty, which is the only route here for replacing one broken knob or testing a finish before committing.
The three 10 packs sit between, and pack size changes more than price. It decides whether spares exist, whether a later kitchen extension can be matched, and whether you find out about a finish problem on one door or on thirty. Only Amerock and Ravinte publish any period at all behind their hardware.
Finishes, Materials and What Each Claims It Suits
Two Listings Name the Metal
Amerock and Ravinte both state zinc. Franklin Brass says corrosion resistant metal without naming it, and adds a claim the others do not make: the finish is scratch and fade resistant, for high traffic areas. Alzassbg says solid and names no material at all. Cosmas publishes no material anywhere, only a high quality satin nickel finish.
That leaves one listing making a durability claim about the finish, two making one about the metal, and two making neither. On a component handled several times a day for years, the finish is the part that fails first, and only Franklin Brass addresses wear directly.
The Style Claims Are the Least Checkable Thing Here
Ravinte names farmhouse, vintage, traditional and transitional. Franklin Brass names vintage, shabby chic and French Country, and goes further by saying its heirloom silver suits darker appliances and backsplashes and muted palettes like pastels and warm neutrals. Amerock names traditional and says the burnished brass coordinates with finishes from top plumbing and lighting brands.
None of that can be verified from a listing, and all three are round metal knobs in different finishes. Alzassbg and Cosmas make no style claim whatsoever, publishing dimensions and screws instead, which is the more useful trade for anyone matching existing hardware rather than starting fresh.
Which One Fits Your Kitchen
Doors and drawer fronts of different thicknesses. Alzassbg is the only pick supplying two sets of screws, 1 inch and breakaway, and telling you to cut them with pliers if needed. It publishes 1.46 inches overall, 0.6 inches of width and 0.8 inches of projection, in brushed satin nickel, ten to a pack.
One knob, or a test before a whole kitchen. Amerock is the only single knob here, 1-1/4 inches or 32 mm in zinc with a burnished brass finish, a limited lifetime warranty and the only usable dimension fields on this page at 1.25 by 1.25 by 1.13 inches.
A knob that stands a full inch proud. Cosmas publishes the most complete set of small figures, a 1-1/8 inch diameter, 1 inch of projection and a 5/8 inch base, in satin nickel with 1 inch screws polybagged in. It publishes no material and no weight.
Every cabinet in the house at once. Ravinte is 30 matte black zinc knobs, 1-1/4 inches across with a 3/4 inch base and 7/8 of an inch of height, with a 365 day evaluation period. Its bullets never mention screws, so check what arrives before booking the weekend.
A muted finish against dark appliances. Franklin Brass is ten flat top knobs at 1-3/16 inches or 30 mm, with ten 1 inch screws, a corrosion resistant metal it does not name, and the only scratch and fade resistant claim on this page.
What We Could Not Verify
Every figure above comes from the makers’ own listings. These are the things we went looking for and could not source.
- No weight comparison is possible here, because the three published weights cover one knob, ten knobs and thirty knobs respectively.
- Four of the five are multipacks whose published dimension fields describe the carton, so only Amerock’s fields describe a knob.
- Amerock and Franklin Brass publish no projection and no base diameter, so neither can be matched to existing hardware marks.
- Ravinte never mentions screws anywhere in its bullets, despite selling thirty knobs in one box.
- Alzassbg and Cosmas publish no material at all, only a finish, so what the knob is made of is unknown on both.
- No listing states a maximum door thickness its screws will suit, and only one offers screws that can be shortened.
