Why do tiles render wider in the web part?

[Vanessa Martin9]

Hi Folks,

The tiles view in the list has the desired appearance:

When added to a page as a web part, the item is wider:

Any idea of why?

Thanks.

@Vanessa Martin9 Are you using width of tile in pixels (px) or in percentages (%)? Try using fix width/height and see if it works.

@ganeshsanap I am a true newbie to JSON. I am not sure which width you mean. Does the width:250 need to be width:250px? This is my code, which allows the tile to be a link:

@Vanessa Martin9 I just checked in documentation, height/width values are by default in pixels only: 

Refer this documentation for gallery/tile view customization: Gallery layout customizations

I found that tiles assume different sizes depending on the type of column they are in. The JSON primarily controls how the tile looks when viewed on the "list" page.
