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 P1000 and Nikon A1000 side-by-side from the front, back and top in their relative dimensions. Nikon P1000 has external dimensions of 146 x 119 x 181 mm (5.75 x 4.69 x 7.13″) and weighs 1415 g (3.12 lb / 49.91 oz) (including batteries).

Now lets look at the top view comparison of Nikon P1000 and Nikon A1000.
Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Nikon A1000 is significantly lighter (1085g ) than the Nikon P1000 which may become a big advantage especially on long walking trips.
