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 Canon SL2 and Canon T8i side-by-side from the front, back and top in their relative dimensions. Canon SL2 has external dimensions of 122 x 93 x 70 mm (4.8 x 3.66 x 2.76″) and weighs 453 g (1.00 lb / 15.98 oz) (including batteries). Canon T8i has external dimensions of 131 x 103 x 76 mm (5.16 x 4.00 x 2.99″) and weighs 515 g (1.14 lb / 18.17 oz) (including batteries).
Below you can see the front-view size comparison of the Canon SL2 and the Canon T8i. Canon SL2 is clearly the smaller of the two cameras. Its body is 9mm narrower, 10mm shorter and 6mm thinner than Canon T8i.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon SL2 is 62g lighter than the Canon T8i 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 Canon SL2 and Canon T8i have the same Canon EF/EF-S lens mount and APS-C sized sensors, lenses will not be a differentiator on total size of the system.
Weather Sealing
Unfortunately neither the Canon EOS Rebel SL2 (EOS 200D / Kiss X9) nor Canon EOS Rebel T8i (EOS 850D / EOS Kiss X10i) provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Canon SL2 and Canon T8i's LCD screens have the same diagonal size of 3.00 inches.
Both cameras feature
Fully Articulating screens where you can change the angle of the screen to make it easier to shoot from waist or over-the-head levels. Fully articulating screens are also useful for taking Selfies and video.
