Creating a sampling grid

lolo

I'm looking to develop a sampling plan so I need to make a grid over top of my site area that is 100mx100m.

I've made a polygon and use "Create Fishnet" however every time I do this there is just a very small rectangle that shows up outside of the polygon (pictured below, the red circle is the output I get).

Looking for suggestions on how to fix this or what other tools I could use to make a grid in arcgis pro or other things.

There's another similar tool you can try if you find Create Fishnet too confusing

Generate Tesselation

Ensure that there is only one feature part (Zoom into the area of the small rectangle to ensure that there is no sliver present.

Also I would recommend the polygon you created to be reprojected to Projected Coordinate System (not web mercator).

For template extent, select the polygon layer that you created.

Keep Cell Height and Width as 100 m each.

And No. of Rows and Columns as 0.

Because your template extent is tiny. Use the dropdown to use an extent the 'same as display' or 'same as layer xyz'

The bigger issue is that you're currently using a geographic coordinate system. switch to UTM or whichever appropriate planimetric coordinate system for your area. You can then ensure the 100m length by adjusting the cell width and cell height properties.
