There is a minimum amount of distance that should be adhered to if your creating tap targets. This is the lifted text from Googles recommendation on appropriately sizing tap targets. These guidelines apply if your making tap targets (two components, like links, that the user can tap on). If they are just normal components (and not links or buttons), there is no minimum “gutter” space that should be adhered to. It should be whatever space looks aesthetically the best.
Small or tightly packed links or buttons are more difficult for users
to accurately press on a touchscreen than with a traditional mouse
cursor. To prevent users from being frustrated by accidentally hitting
the wrong ones, tap targets should be made sufficiently large and far
from other tap targets that a user can press them without their finger
pad overlapping any other tap targets. The average adult finger pad
size is about 10mm wide (a bit less than half an inch), and the
Android UI guidelines recommend a minimum tap target size of roughly
7mm, or 48 CSS pixels on a site with a properly-set mobile viewport.
You should ensure that the most important tap targets on your site—the
ones users will be using the most often—are large enough to be easy to
press, at least 48 CSS pixels tall/wide (assuming you have configured
your viewport properly). Less frequently-used links can be smaller,
but should still have spacing between them and other links, so that a
10mm finger pad would not accidentally press both links at once. Users
should not have to pinch zoom (or rely on other browser UI features
for disambiguating finger taps, such as Chrome’s popup magnifying
glass) in order to easily and reliably press the desired button or
Make important tap targets large enough to be easy to press
This applies to the tap targets your users will use the most, such as
buttons for frequently-used actions, search bars and other important
form fields, and primary navigational links. These tap targets should
be at least 7mm (48 CSS pixels if you have configured your viewport
properly), and should have additional spacing around them if they are
any smaller than 7mm.
Ensure there is extra spacing between smaller tap targets
It is reasonable for infrequently-used links or buttons to be smaller
than the recommended size of 7mm, but there should still be no other
tap targets within 5mm (32 CSS pixels), both horizontally and
vertically, so that a user’s finger pressing on one tap target will
not inadvertently touch another tap target.
