I prefer stacked way.

Thank you

What's in the adjoining rooms? You want to be consistent.

You just started another post with the exact same question and photos?

Sorry about that.

There’s hard wood in the dining room. And there’s a step down into the sunroom. Haven’t decided on flooring for sunroom yet.

• What is the recommendation on the installation instruction??????
• Some tiles cannot be stacked unless they are 'rectified' edges' The grout line spacing has to be larger to accommodate tiles that don't have rectified edges.
• Some tiles cannot be overlapped at 50% but only 1/3 due to lippage.

You need to answer these questions before you make your decision

Stacked will make the space feel larger! Keeping the grout color similar to the tile color will really add cohesiveness.

What size are the tiles? I used a basket weave tile layout that created a square layout using rectangular tiles. This design opens up my small kitchen. People comment on the design. It's much more interesting than either stacked or running.

BASKETWEAVE PATTERN

In it’s purest form the Basketweave tile pattern is two brick-shaped tiles set horizontally against two brick-shaped tiles set vertically. It’s a simple and easy pattern to achieve and offers a textured field without too much effort.

Somewhat more labor-intensive and much more textured in appearance, the other Basketweave version is where brick-shaped tiles are set in an interlocking pattern with smaller square tiles filling the space in between.
