Section thickness
The thickness of a bicycle lock's cross-section indicates how sturdy its main protective component is and generally helps understand the balance between convenience and protection level. Typically, thinner options, such as around 6-8 mm, are easier to carry and simpler to secure, while more robust sizes like 10-12 mm and above are associated with higher resistance to force. In practice, a thin bike lock is more suitable for a short stop at the store, whereas a thicker one is better for daily bike storage in the city.
Thickness can refer to different structures simultaneously: for cable models, it's the thickness of the cable; for chain locks, it's the size of the links; for shackles, it's the thickness of the metal shackle. It's better to compare figures considering the type of lock because 10 mm in a cable and 10 mm in a shackle are not the same in terms of actual protection.

Shackle size
Dimensions of the shackle in a U-lock or padlock (see "Type").
In the first case, only two parameters are usually indicated — width and length (height), most often in that order, but sometimes vice versa. However, it is not difficult to determine where what size is — the length is longer, this is due to the purpose of the lock. It usually varies from 130 – 140 to 300 mm, width — from 80 to 115 – 120 mm. A larger shackle gives more options for attaching the bike (it will “get” further and be able to cover a larger object), however, the lock also turns out to be bulky and heavy. Shackle thickness for U-locks is listed separately (see below).
But in padlocks, all three sizes are usually called, including the thickness. Here, the width and length most often differ slightly, by a couple of millimetres, although there are exceptions, with an elongated bow. Anyway, this parameter is not as important for such locks as for U-locks: firstly, hinged models are miniature by definition, and secondly, the difference in size is not particularly critical for their main purpose (shackles 20x20 and 30x30 mm are the same effectively fasten the ends of the "average" cable or chain).
