wheelchair, cane + forearm crutches, walker 90% chance if you're hesitant to draw mobility aids you're overthinking it. start somewhere. obviously these are not detailed references.
wheelchairs and walkers should be proportioned like chairs. in most cases canes are held on the opposite side of the painful leg because you want to put weight on the cane instead of the leg (dr house lied to you) but depending on the reason for the cane this can change!
[ image id: a title image that reads "learn how to draw mobility aids very fast" followed by three simplified drawings of different mobility aids broken down into two steps each. the changes made in each step are colored red.
the second image shows a wheelchair, with the steps "1. seat with footrest", showing a simple chair shape, and "2. wheels", which adds two large wheels to the back and two small wheels to the front.
the third image shows both a cane and forearm crutches, with the steps "1. stick", showing a single line of color, and "2. add handle", which shows a hand grip and a forearm rest on two different sticks. and additional label below this step reads "handheld stick height is where the hand rests at the hip" and "forearm stick height is the forearm".
the fourth image shows a walker, with the steps "1. platform with wheels", showing a backless chair shape with a wheel on each leg, and "2. add handlebar", which shows a handle raised above the seat. end id ]
β¨ edited to remove italics for screen readers + also pointing out that I missed the handle on the forearm crutches! always use real reference photos when you can, this is just a starting point to help you understand the basics if you're not familiar :3
you see it's not the wheels i can't draw, those are ez, it's the GODDAMN CHAIR
well you can just ask for help for that too! :3
1. One square for the seat and one for the back
2. Distort the seat square until it looks correct for the scene
3. Resize the back square to match and connect it to the seat
4. Add legs or wheels or whatever
If you're having trouble with seat height, resize the whole thing so that:
- The red back square is about the shoulder to hip height of your character, or
- The distance from the edge of the blue seat square to the ground is about the same as the character's knee to foot height!
it varies based on specific chair designs (especially with different types of wheelchair! Back height depends on the purpose of the chair), but that should get you in the right ballpark :) hope this helps!
