Use this y+ calculator

Based on your inlet flow parameter and using y+ = 1 get the desired first cell wall spacing. Use that spacing with a ratio of 1.2. You can use any bunching law as long as the final solution is grid-independent. The important point is if you are using low-Re models you should ensure your y+<1.

Remember, y+ is a post-processing parameter and so you must check after you get the final solution if the y+ on wall is less than 1 or not otherwise you may have a smaller first cell-distance.
