How to fix the board to adjust according to screen sizes in android game?

Hello All,

I am making a board game in android using unreal engine. The board is always fixed and players move their pieces at their turn. Similar to chess.

I want to fix the board similar to the image I am attaching in this question and if we fix the board, how to mark the blocks so when players moves, the piece goes exactly to that block?

I want exactly like this

Thanks in advance.
