Size and weight are big decision factors when you are trying to find the ideal camera for your needs.
In this section, we are going to illustrate the Nikon D3X and Nikon D6 side-by-side from the front, back and top in their relative dimensions. Nikon D3X has external dimensions of 160 x 157 x 88 mm (6.3 x 6.18 x 3.46″) and weighs 1260 g (2.78 lb / 44.45 oz) (including batteries). Nikon D6 has external dimensions of 160 x 163 x 92 mm (6.3 x 6.42 x 3.62″) and weighs 1270 g (2.80 lb / 44.80 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon D3X is 10g lighter than the Nikon D6 but we don't think this will make a significant difference.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you also have to take into account the lenses that you will be using with these bodies. Since both Nikon D3X and Nikon D6 have the same Nikon F lens mount and Full frame sized sensors, lenses will not be a differentiator on total size of the system.
Weather Sealing
Both the D3X and the D6 have weather sealings in their bodies, making them resistant to water and dust.
LCD Screen Size and Features
Nikon D6's 3.20" LCD screen is slightly larger than Nikon D3X's 3 screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
