Hi! Thanks for your question 😊
The assets in this pack are individually categorized so you can work with them and rescale them flexibly to multiple resolutions, depending on what your project needs. They don't come with a fixed tile width, tile height, margin, or spacing specifically set up for Tiled, since the idea is to give you the freedom to adjust them to your own grid.
If you'd like a more detailed guide on integrating them into Tiled, feel free to reach out to me at the email listed on my profile. Happy to help!
