When I'm setting up a small breadboard (400 point) with a Nano, I often find myself having to run wires that are between 1" and 2" or point distances between 10 and 20 spaces on the breadboard. I have a few different sets of preformed breadboard jumper wire that you can find online and in stores and they all seem to follow the same lengths and color standards, but for whatever reason, they don't have lengths that I find useful for Arduino work. Why is that? Historical reasons? Am I doing something wrong? I've made this diagram using Tinkercad to show what I mean. In it, I show the various lengths of jumper wire that are often provided.

Diagram of different size jumper wires on a breadboard

I realize that I can use other types of jumper wires or make my own, but the main reason for buying the preformed ones are that they are fast, compact and hug the breadboard. Also, the 2" length ones aren't even the right size to connect the power rails on both sides so why not make them 1.8" length instead of 2.0" length? I have seen other people do the same thing of using a 2.0" length wire and bending it slightly to connect the power rails.

I've searched online for other people asking this same question and didn't find anyone else complaining so I'm wondering if I've been using them wrong all this time. :/

    I always have a shortage of small wires and too many long ones. Also I would like to have multiple colors for same length (like red for VCC, black for GND etc). – Michel Keijzers Mar 18 '19 at 11:09

    buy or scavenge a wire in any color, cut a length you need, strip the ends, bend the ends, ready – Juraj Mar 18 '19 at 12:24

    your wires are still straight and hug the breadboard? quaint. ahh, to be young again... – dandavis Mar 18 '19 at 17:46
