For a personal statement, LSE says maximum two pages, and not more than 1000-1500 words. I'm pretty happy with my 700 words. I could stretch it out but I feel I would be adding redundant information. Anyone has experience with a personal statement to LSE?

If there's no minimum requirements, and you're happy with it as it is, I don't see any reason to add unnecessary information. Only add to it if you have something important to say.

I have experience. I applied last year and got an offer but I had to defer in the end. I remember I exceeded the word limit. I believe they really do not care about the length but the quality and the content.
