How to Set Actual Size for Graphics Layer?

[AliRezaShahvaran]

I would like to draw a square using 'Graphics Layer', but when I attempt to set its size to 1m by 1m using the properties of the drawn object, it becomes excessively large. The attached screenshot shows that a 1 x 1 (units unknown) square is being displayed as 111.11 km by 111.11 km!

I'd guess your dataframe (map coordinate system) is in a Geographic coordinate system such as WGS 1984.  The map units will be planar equivalents of 1 degree at the equator (111km).  Change to a planimetric coordinate system and set the properties, then switch back if necessary.

You could also create a feature with set length and width and convert to graphic after.
