The size of the dictionary trezor uses is 4096 words.
Slight correction... The BIP39 wordlist has 2048 words... And the seeds used by Trezor (and Ledger) are 24 words... Providing 256bits of Entropy.

You are right.. had 2^12 in my mind instead of 2^11  Roll Eyes

But it may be worth to add that a 12 word seed with 128 bits of entropy is still safe enough because bitcoins 256 bit ECDSA keys have 128 bits of keystrength.
So anything above 128 bit isn't necessary. It mostly just has a psychological aspect.
This, at least, applies to most of the curves. A few seem to offer a lower level of security.
