I've been reading around and people have been saying some lens' aren't meant for full framed bodies whereas some are meant for it or vis versa with the cropped framed bodies.

Could some explain to me why this is and how I know what to buy for future reference?

By the way, I use a t3i

To keep things simple -

ef-s lens = crop body only
ef lens = both crop and ff

note - ef lens *might* perform slightly different when used on crop vs ff

EF-S lenses may only be used on Canon EOS cameras with 1.6X sensors newer than the 10D. Such bodies are marked with a white dot on the lens mount, similar to the red dot for EF lenses.

3rd parties also offer small format lenses that are only intended for 1.6X sensors as well. These lenses will usually mount on FF and 1.3X bodies (unlike the Canon EF-S) but they will not give full coverage of the sensor.

There are some lenses (anything with an 'EF-S' designation) that will not physically work on FF bodies because they interfere with the swing of the larger mirror.

Some people insist that some lenses were designed for FF and are not as suitable for a crop sensor because of awkward FoV zoom ranges when you consider the crop factor. Whether or not you find it awkward is personal preference.

your t31 is a crop camera therefore you want efs lens , but that doesnt mean you cant
use ef lens on there as well, but you cant use efs lens on full frame camera

so understand if you move to a full frame camera, your efs lens wont work on it .

if you use a ef lens which is 24 105 for full frame the focal distance on a crop is X 1.6 which in reality for a crop is 38.4 168

here is a link you should read

I think you meant to say the equivalent field of view. Focal distance doesn't change based on what camera the lens is mounted on.

No. That would be wrong - the focal lengths will not change, but the field of view will.

The Image Circle size (how big of a circle is filled with light at the focal plane) either covers or does not cover the different size frames of APS-C vs. FF cameras. The circle can be smaller and still cover 15x23mm (approx) size of APS-C, compared to the 24x36mm size of FF frame.

Generally, it is the image circle size which is designed to cover 24x36mm or not. EF-S is the designation by Canon for lenses which would not cover 24x36mm. EF-S lenses have a number of other characteristics which make them not suitable for FF cameras.

Examples of other Canon EF-S differentiators,
1) how far into the camera body that the rear optic protrudes,
2) whether or not the lens mount can be inserted into a FF body.

Other manufacturers have only the Image Circle as the only differentiation, not matching Canon's other differentiators. Other designators by other manufacturer are used to indicate 'limited image circle size', like Tamron uses 'Di-II' for this.

Other than the fact that Canon EF-S mount lenses cannot be used on cameras other than those which they were designed for (APS-C format cameras beginning with production of the 300D - the original "Digital Rebel"), the majority of the recommendations that I believe Jay is referring to come from people's personal preferences as to focal length ranges that they prefer to use.

A typical example that we see frequently is "the 24-70 is not a good lens to use on a 7D". These folks suggest, instead, the use of a lens with a range of 17 or 18 mm to maybe 50 or 55 mm because the "24-70 is not wide enough on a 'crop' camera". This sort of recommendation should be totally ignored, in my opinion, because it's really based on personal preference. I, for example, find my 24-70 an extremely useful focal length range for use on my 20D.

For the newbies - this information, as presented, is quite incorrect.
