What would you consider a correct dividend %, and why?

I understood that a stock offering too much dividends or not enough (or simply not) can say a bit about how the company's liquidity is managed. I understood that offering too much dividends can compromise the business's development because not 'enough' money is reinvested, etc.

Suppose you're setting up a dividend portfolio, what would be the ideal dividend % when choosing a stock? Does it depend on the company's sector and other variables? What would be the ideal average dividend % of the portfolio?

EDIT: TO BE A CORRECT DIVIDEND %* TITLE
