1" (25mm) Slacklines
Used since the 1980s, 25mm webbings were used when slacklining became a thing. They're generally more dynamic (elastic) than 50mm webbings and favor a slower, focused and deep practice akin to yoga and meditation.
2" (50mm) Slacklines
50mm webbings entered the slackline world in 2008. They're mostly used for tricklining, an acrobatic discipline which involves jumping on the line to realize aerial tricks. The larger webbing offers more comfort when the body hits the line. Contrary to popular belief, a 50mm webbing is not easier to walk than a 25mm one. The factors that really affects difficulty are the height, length, tension and webbing type (elasticity and weight) of a slackline.
