Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Nikon D3000 and Nikon D3100 side-by-side from the front, back and top in their relative dimensions.
Below you can see the front view size comparison of Nikon D3000 and Nikon D3100. Nikon D3100 is 2mm narrower and 1mm shorter than Nikon D3000 but it is also 11mm thicker.
Here is the back view size comparison of Nikon D3000 and Nikon D3100.
Now lets look at the top view comparison of Nikon D3000 and Nikon D3100.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Nikon D3100 is 31g lighter than the Nikon D3000 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 have to also take into account the lenses that you will be using with these bodies. Since both Nikon D3000 and Nikon D3100 have the same APS-C sized sensor, their lenses for a similar focal length and aperture will be similar in size and weight.
