# When I need thicker tracks than standard, does track widths need wider?

_Published: 2016-08-12_

Yes, in general, if you need the copper base thicker, the wider the track should be. One rule of thumb is that with a 18 µm copper base the track should not be narrower than 0.1 mm (4 mil) and with a 105 µm copper base the track should not be narrower than 0.25 mm (10 mil).
