are all sim cards the same size?

Is the 3g sim from the iPhone and a prepaid AT&T sim the same size?

It's a standard size (see GSM 11.11 below)

Two physical types of SIM are specified. These are the "ID-1 SIM" and the "Plug-in SIM".
The physical characteristics of both types of SIM shall be in accordance with ISO 7816-1,2 [23, 24] unless
otherwise specified. The following additional requirements shall be applied to ensure proper operation in
the GSM environment.
4.1 Format and layout
The information on the exterior of either SIM should include at least the individual account identifier and the
check digit of the IC Card Identification (see clause 10, EF
ICCID).
4.1.1 ID-1 SIM
Format and layout of the ID-1 SIM shall be in accordance with ISO 7816-1,2 [23, 24].
The card shall have a polarisation mark (see TS GSM 02.07 [3]) which indicates how the user should
insert the card into the ME.
The ME shall accept embossed ID-1 cards. The embossing shall be in accordance with ISO 7811
[20, 21]. The contacts of the ID-1 SIM shall be located on the front (embossed face, see ISO 7810 [20])
