Pad diameter and line width in svg files

Hi, I’m learning in doing custom parts. I downloaded the FontsAndTemplates folder from the Fritzing site, where a pad (in the PCBViewGraphic_Template.svg) has a diameter D of 0.048 inches and the line width W is 0.013 inches.

I compared it with other parts in the fritzing/parts/svg/core/pcb folder, and I realised that these measures are often not followed, for example:

AD22100.svg = D: 0.075 W: 0.020
Arduino_Nano3_pcb.svg = D: 0.056 W: 0.014
sparckfun_connectors_2x5.svg =D: 0.074 W: 0.017
3mm_LED.svg = D: 0.063 W: 0.016

I was wondering if there are some minimum and maximum limits to not exceed!

This is for finished part sharing, could you please edit your post in the drop down box and move it to part help.

Things are kind-of all over the place because of different authors, files converted from EagleCad, and such.

If you want a more consistent std hole and pad size I would check the Core parts, but even they aren’t super consistent.

We are supposed to use std recommendation, but even I don’t follow it because the 0.5mm outlines are too think in my opinion.
