The price is the same for registration, but it is more difficult to register a two-character trademark (currently there are too few trademark resources for two-character trademarks); but if you buy it, of course the price for a two-character trademark will be higher than that of a three-character trademark. The word has four characters. Of course, it also depends on the specific circumstances, such as category, product options, trademark recognition (whether it is easy to remember and recite), etc.
