Sport kites can be designed to fly in a wide range of conditions. Many standard kites fly best in winds from {{convert|1.5|to|6|m/s|km/h mph|abbr=on|sigfig=2}}. "Ultralight" and "super ultralight" designs are made from lightweight materials that can be flown in the slightest breeze or even [[indoor kite|indoors]] with calm air. High wind kite designs are often made with mesh panels or an "air brake" attached to the lines to fly in higher winds up to approximately {{convert|20|m/s|km/h mph|abbr=on|sigfig=2}}. Wind ranges depend significantly on the skill of the pilot; novice or first time fliers may have difficulty keeping a kite airborne believing the wind is too light while experienced pilots nearby are performing acrobatic tricks in the same wind. For smooth and consistent flying a steady breeze is required, uninhibited by trees, buildings, hills, or other tall objects which may block the wind.<ref>{{cite web|url=https://www.gkites.com/howtofly/sl-htf.html|title=How to Fly a Kite|website=gkites.com}}</ref>

Professional quality kites are made from multiple synthetic materials. Kite sails are primarily made from lightweight [[ripstop polyester]] which has been chemically treated to minimize stretch, repel water, increase airtightness, and be UV resistant. Edge material is often heavyweight [[Dacron]] or [[Kevlar]] to provide reinforcement and strength. Kite frames typically use wrapped [[carbon fiber]] tubes which are lightweight and stiff, yet can flex to absorb strong wind forces and survive hard crashes. Kite lines are made from ultra-high-molecular-weight polyethylene like Spectra or Dyneema woven specifically for kite line to have minimal stretch under tension and slip over itself even when wrapped over itself many times from kites spinning midair. Some have wingtip and tail weight attachments which change the flight characteristics of the kite, making some advanced maneuvers easier or more dramatic. Reinforcements and connectors may be made from nylon, Mylar, aluminum, and similar materials.<ref>{{cite web|url=http://www.kitestop.com/blog/post/what-makes-a-good-kite/|title=What makes a good kite?|website=kitestop.com}}</ref><ref>{{cite web|url=https://kite.org/education/kite-resources/kite-plans/kite-fabric-what-you-need-to-know/|title=Kite Fabric - What You Need to Know|website=kite.org}}</ref>

A dual-line kite can range from $50 for a beginner kite, to over $300 for competition and performance quality kites. A quad-line kite can range from $150 for a beginner kite to over $400 for professional quality kites. Flying lines are commonly from $50 to over $100 per set.

Some kite designs may be classified as [[power kite]]s and traction kites, which can be used to tow wheeled [[kite buggy|kite buggies]] ([[kite buggying]]) or [[surfboard]]s ([[kite surfing]]). Power kites vary in size from "trainers" which often have dual-lines and a small sail area, to large full size traction kites with four lines, designed to pull people on [[kite board]]s or vehicles. Many of these strong-pulling designs include a safety strap which can be engaged in emergencies to release or depower the kite, with some designs adding an additional (third or fifth) line for this purpose.<ref>{{cite news|url=https://www.surfertoday.com/kiteboarding/how-to-quick-release-and-depower-a-kite|title=How to quick-release and depower a kite|newspaper=Surfertoday}}</ref>{{clear}}
