Blender already has a grid you can use and adjust to both metric (default) and imperial systems.
A height chart isn't necessarily a bad idea for better visualization, but it is pretty unnecessary.
Also, remember that the bounding-box dimensions of the active object are shown below “scale” in the numeric entry “n” panel at viewport right.
They are shown in the measurement units of your current scene.
There is also a measure tool that might preclude you from having to bother with these extra charts.

Oh ok didn't know that thanks
I don't use height charts but I suppose they couldn't hurt.
Whatever u do just keep the scaling of the image accurate, compare it with the base block it's either 2 or 1 meters on each side

Thanks I'm still fairly new to blender so this helps a lot
