These icons have the very same width in Sketch:
When I export them as PNGs (3x size), the inbox icon has a width of 69px, while the trash's width is 63px.
Why is that? Why don't they have the same width when exported?
Could it be that the inbox icon has a stroke which changes the width for 6 px? for 1.5px on each side. I haven't used sketch at all
