An ISL frame can be as big as 1518 + 30 = 1548 bytes. The original frame is encapsulated in a 26-byte header and a 4-byte CRC.
An 802.1Q frame can be as big as 1522 bytes. 802.1Q inserts a 4-byte header immediately the destination and source MAC addresses (and source-routing information, if present) of the frame to be transmitted, which could have already been 1518 bytes.
