The diameter is about 0.29 nm. The atomic diameter can be determined from interpolation of the effective ionic radii of the isoelectronic ions (from crystal data) of O2- (2.80 Å), OH- (2.74 Å) and H3O+ (2.76 Å). Coincidentally, this diameter is similar to the length of a hydrogen bond. The water molecule (bond length 0.96 Å) is smaller than ammonia (bond length 1.01 Å) or methane (bond length 1.09 Å), with only H2 (bond length 0.74 Å) and HF (bond length 0.92 Å) being smaller molecules.
