I don't understand why my forearms are disproportionately small in comparison to my upper arms. I've been doing wrist curls, and I'm not noticing a difference in intensity my forearm gets by just doing bench presses. Am I missing something here?
You aren't suppose to be isolating forearms, who does that?
All jokes aside, if you want your forearms to grow, you need to be doing deadlifts. When you're gripping 300-400 pounds with no straps, your forearms will explode. Expect callus tears as well.
Besides this, I noticed underhand grip pullups really got my forearms to grow over the past 3 1/2 years. Naturally they were never a problem. Hope I've helped.
How long have you been lifting?
Wrist curls are kind of meh for forearms, try doing your workouts with a thicker bar and you will definitely notice your forearms increase dramatically.
First thing it to think of the function that the muscles in the forearms (brachioradialis) perform. The forearms, along with both heads of the biceps are responsible to supinate, pronate, doriflex and palmarflex the wrist joint. There is also a small degree of elbow flexion involved with the forearms function, however it's primarily the function of the bicep. So they key is to include exercises that do that. An example would be, barbell curls, alternating dumbbell curls (twisting/supinating your wrist as you perform the concentric part of the repetition) and a variation of a hammer curl)
Putting the brachioradilais under isometric stress is also very good way if not better way of developing forearm strength and size. This can be done but not using straps (they're dumb and a waste of time). Include deadlifts and it's variations, farmers walks, wrist rollers and stop using straps.
If non of the above seem to make much of a change the issue may be with your genetic muscles shape and insertion points and joint lengths, in this case it's regarding the length of the humerus, radius and ulna.

Try getting better genetics.
See response above. I do deadlift, and I've only felt the sting in my back/hip/leg, never really in my arm. I've been lifting on and off for 3 years now. Keep in mind that I'm turning 19 this month.
I think you don't have to isolate them by doing wrists curls, forearms are also worked out when doing compound movements.
Whether the movement is multi-joint or not they are going to be worked regardless, even some isolations. If you have to grasp something, your forearms are activated to a certain degree.
This guys forearms are lagging, therefore implementing isolations and other exercises will benefit him greatly.
keep doing forearm curls rep out at the end of your sessions. also do reverse grip (as if you where working tris) bycept curl with a bar.
you can also use a ash pole with your arms fully extended out to the front rotate the bar (twist it with your hands) do both directions.
genetics is just an excuse.
