Max gap size for effective drywall joint compound
You'll be fine, though you might want to go buy a bag of setting type (dry powder, mix with water - sets, rather than drying out like the stuff in a bucket) joint compound, both because it's the right type for use with mesh tape, and becasue of this tid-bit from USG:


  Open spaces between panels of 6.4 mm (1/4) or more should be filled with compound at least 24 hours prior to embedding or first-coat work. Setting-type joint compounds, which are hardening types, are recommended for these large fills. With these setting-type compounds as a fill, joint treatment may begin as soon as the compound has hardened, eliminating the typical 24-hr. drying period.
