Door Knobs and Rings

Door knobs and pull rings compared

This group covers two ways to open an interior door by hand: a round knob you turn, or a pull, sometimes called a ring, that you grip and push, part of Knobs.co's larger cabinet hardware catalog. Rocky Mountain Hardware makes both styles shown here, with knob shapes like Smith, Squash, and Roswell sitting alongside straight door pulls in 2 1/2", 3", and 4" lengths. A few knobs, including the Round Crystal and Round Cast Glass options, swap metal for glass, which changes how the piece catches light without changing how it functions.

Knob shape, not just knob size

Squash and Roswell describe the knob's silhouette rather than its dimension: Squash reads flatter and wider, close to its name, while Roswell keeps a rounder, more classic profile. Mini Roswell shrinks that same shape down for a smaller door or a cabinet-adjacent spot, anywhere a full-size knob would look oversized. None of these differences affect installation, only how the knob looks from the other side of a room.

When a pull works better than a knob

A straight pull takes less wrist movement to operate than a knob you have to grip and twist, which matters on doors used constantly or by anyone with limited grip strength. The lengths here, 2 1/2" through 4", scale with the door's weight and the hand using it; a heavier passage door generally suits the longer pull. Crystal and cast glass knobs, by contrast, are chosen for how they look under light more than for daily ergonomics.

Ordering around an existing bore

Interior doors are almost always pre-bored to a standard diameter, so a replacement knob or pull has to match that existing hole, not the size of whatever piece is currently installed. Check the bore size first; skipping that step leads to a mismatch that only shows up once the old hardware comes off. Interior doors in most homes use one of two common bore sizes, and hardware sized for the wrong bore either sits loose in the hole or won't seat at all, no matter how well the style matches everywhere else.

Mixing knob and pull hardware in one house

Running knobs on some doors and pulls on others is a legitimate choice, not a mistake, since the two functions suit different rooms. A closet or pantry with light daily traffic works fine with either, while a hallway door that gets opened many times daily is a reasonable place to standardize on whichever style is easier on the hand. Keeping the finish consistent across both matters more than keeping the shape consistent.
