What notch type/size for this tile please? - Tile Advice

[Arseneknows]

I am a DIYer so please bear with me, this is my first floor tile project which happens to be our bathroom.

Its a small tile area of no more than 1.8 x 1.5 m , the floor is timber but very solid and flat. I laid Ditra matting on top so is now ready to be tiled.

The tiles are 20x20cm glazed porcelain, 10mm thick with a rather flat back to them. What type of trowel and notch size is best suited for this? I only have a few trowels 4mm. 6mm, and 10mm square notched but will go out and buy a new one if none of these are suitable.

Thanks in advance.

10mm will suffice 👍

Thanks. I'll give that a go. I was erring on side of the 6mm one but I guess that may not provide enough coverage?
