Dimensions and weight

DimensionsiOne unit in its normal position, with antennas folded flat or removed. Height is bottom to top. For a round unit, width and depth are both the diameter. A size the maker prints with antennas up goes in Dimensions with antennas.

Tom's Hardware prints 9.06 x 5.28 x 2.20 in (230 x 134 x 56 mm) and says it does not count the antennas, and Amazon prints 9.06 in L x 5.28 in W x 2.2 in H. So 230 mm is the width, 134 mm the depth and 56 mm the height with the antennas not counted.

Width110Height254Depth211mm(4.3 × 10 × 8.3 in)2Maker spec sheet (PDF)downloads.netgear.com/files/GDC/CAX30/CAX30_DS.pdfRead 15 October 2026Printed 10.0 x 8.3 x 4.3 in / 254 x 211 x 110 mm without axis names. The manual says the status LEDs and buttons are on the front, and in the product photo they sit on the narrow edge. Amazon prints 8.3 in L x 4.3 in W x 10 in H. So 254 mm is the height, 211 mm the depth and 110 mm the width. The April 2021 manual (Table 6) prints 264 x 215 x 110 mm. The newer data sheet and the netgear.com page agree, so the data sheet is used.
