Check frame limits. - [Inline Skate Buying Guide: Boots, Frames, Wheels and Sizing](https://skatetested.com/guides/inline-skate-buying-guide): Choose inline skates by use: recreational skates have comfortable soft boots, heel brakes and 72 to 84 mm wheels; fitness skates use larger 90 to 110 mm wheels for speed; urban skates have hard boots and maneuverable frames; aggressive skates have small wheels and grind plates. Outdoor wheels around 82 to 85A balance grip and wear. Size by the maker's chart, with a snug heel. - [RKP vs TKP Longboard Trucks: Which Setup Fits?](https://skatetested.com/guides/longboard-truck-rkp-vs-tkp): Reverse kingpin trucks are common on longboards; traditional kingpin trucks are common on street skateboards and some compact cruisers. Match axle width to the deck and intended setup. - [Longboard vs Cruiser vs Skateboard: Which Should You Ride?](https://skatetested.com/guides/longboard-vs-cruiser-vs-skateboard): Street skateboards are built for tricks, ramps and skateparks with hard, small wheels. Cruisers are short boards with soft wheels for getting around and portability. Longboards are longer and stable, with big soft wheels and wider trucks for commuting, carving and downhill. Pick by where you ride and how far, not by looks. - [Low-Profile vs Classic Skate Helmets](https://skatetested.com/guides/low-profile-vs-classic-skate-helmets): A low-profile shell and a classic skate helmet can sit differently on the head. Choose by measured fit, coverage, activity certification and the maker’s sizing instructions. - [Outdoor vs Indoor Quad Skate Wheels](https://skatetested.com/guides/outdoor-vs-indoor-quad-skate-wheels): Outdoor wheels are often softer and larger for uneven pavement; indoor wheels are often harder for smoother rink surfaces. Check the floor, wheel dimensions and skate setup. - [Quad Roller Skates vs Inline Skates: Which Should You Learn?](https://skatetested.com/guides/quad-roller-skates-vs-inline-skates): Quad skates have two pairs of side-by-side wheels, feel stable standing still and suit rink skating, dance, roller derby and park. Inline skates have a single row of wheels, roll faster and smoother over distance and suit fitness, commuting and aggressive skating. Neither is strictly easier; pick the one that matches how and where you want to skate. - [Skate Helmet Certifications: CPSC, ASTM F1492 and Dual-Certified](https://skatetested.com/guides/skate-helmet-certification-guide): For skateboarding and trick roller skating, look for a helmet marked ASTM F1492; it is designed to withstand more than one moderate impact, but only a limited number. If you will also bike in the helmet, choose one that also meets the CPSC bicycle standard, 16 CFR 1203. In Europe, EN 1078 covers bicycle, skateboard and roller-skate helmets. Fit the helmet level and snug, and follow the maker's replacement instructions after impacts. - [Skateboard Bearings and ABEC Ratings Explained](https://skatetested.com/guides/skateboard-bearings-abec-explained): Almost all skateboard, longboard and many skate wheels use 608 bearings: 8 mm bore, 22 mm outer diameter and 7 mm wide, eight per board. ABEC ratings describe manufacturing tolerances, not speed or durability under skating loads, and several well-regarded skate bearings carry no ABEC rating. Choose quality steel bearings, removable shields for cleaning, and spacers to keep them aligned. - [Skateboard Deck Size Guide: Width by Style and Shoe Size](https://skatetested.com/guides/skateboard-deck-size-guide): Deck width matters more than length. Narrower decks around 7.75 to 8.0 inches flip easily for street and technical tricks; 8.0 to 8.25 inches is the all-round middle; 8.25 to 8.5 inches and wider gives stability for ramps, bowls and bigger feet. Young kids ride mini and youth decks around 7.0 to 7.5 inches. Match truck axle width to the deck so wheels sit near the edges. - [Skateboard Truck and Wheel Fit: A Setup Comparison](https://skatetested.com/guides/skateboard-truck-and-wheel-fit-comparison): Match truck axle width to deck width, then choose wheel diameter, width and hardness as a separate decision. Manufacturer charts answer different questions, and the assembled setup still needs a wheel-clearance check. - [Skateboard Truck Width vs Deck Width](https://skatetested.com/guides/skateboard-truck-width-vs-deck-width): Truck axle width should be close to the deck width and follow the truck maker’s chart. Confirm how the brand measures width and check wheel clearance on the assembled board. - [Skateboard Wheel Hardness and Size: Durometer Explained](https://skatetested.com/guides/skateboard-wheel-hardness-and-size): Wheel hardness is measured in durometer: soft wheels around 78 to 87A grip and roll smoothly over rough ground for cruising, while hard wheels around 99 to 101A slide and stay fast on smooth skateparks and street spots. Diameter changes speed and clearance: 50 to 54 mm suits street, 54 to 58 mm parks and bowls, and 58 mm and up cruising. Big soft wheels may need risers to avoid wheel bite. - [Steel vs Ceramic Skateboard Bearings](https://skatetested.com/guides/steel-vs-ceramic-skateboard-bearings): Steel bearings use conventional ball and race materials; ceramic models pair ceramic balls with steel races in the Bones examples compared here. Select by the exact product specification and maintenance needs. ## Reader codes - The Bioboards E-Skate discount code is SEBASTIANBASSOL for $80 off at bioboards.eu. Permanent, never expires.
