There is no official list. It's just asking for the rough size of your lexicon, assuming that ~1500 is what's generally needed to be a functioning language. Mind you, I believe it ought to only count content words and not grammatical function words (i.e., only verbs, nouns and adjectives, not pronouns and prepositions, etc.).

I agree with Meuser though, the Swadesh list that comes preloaded with a page is a good start, but I encourage users to eventually create a Lexicon subpage (that is, "conlang.wikia.com/wiki/ConlangName/Lexicon") and expand the lexicon on such a page, and eventually remove the Swadesh list (replacing it with a link to said Lexicon page, or you could leave it there, but personally I find it to be a bit obtrusive).

Do let us know if you need anymore help or have any other questions!
