This is the only tool that recommends BOTH side edge and base edge angles together, matched to your riding style and snow conditions. Most guides only mention side edge. Base edge angle is equally important: it controls how easily the board initiates turns.
What edge angle should I use on my snowboard? Two angles matter: side edge and base edge. All-mountain: 88° side edge, 0.5° base edge. Freestyle and park: 89 to 90° side edge (duller, forgiving), 0° base edge. Freeride and carving: 87 to 88° side edge (sharper, more grip), 1° base edge. A sharper side edge (lower number) grips ice better but catches more easily. A duller edge (higher number) is more forgiving but slides on ice. Select your style below.

💡 Why these angles: All-mountain tuning balances grip and forgiveness. 88° side edge provides reliable carving on groomed snow without catching on variable terrain. 0.5° base edge helps turn initiation while maintaining edge hold.
❄️ Conditions: Standard groomed conditions: your setting is optimized for this.
🔧 Detuning: Lightly detune the tip contact points (first 3 to 5 cm) to prevent tip catch in variable snow. Leave the tail edges sharp for control during carved turns. The effective edge under the bindings stays at full sharpness.
⏱ Maintenance: Sharpen edges every 4 to 6 days of riding, or when you notice decreased grip on groomed turns. A diamond stone touch-up takes 5 minutes and extends time between full tunes.
For reference only. Adjust 1° at a time and ride the new tune for 2 to 3 days before changing again. Edge work is permanent: removed metal does not grow back.
Freestyle riders need dull 90° edges for rails; carvers need sharp 87° edges for ice grip. The table below covers five riding styles.

What Is Side Edge Angle?
Side edge angle is the angle between the metal edge and the base of the snowboard, measured from the side. Lower number means sharper edge means more grip. Factory boards typically come at 90° (flat). Every degree sharper (89°, 88°, 87°) increases the edge's bite into snow. Think of it like a knife: a 90° knife is dull, an 87° knife is sharp. On ice, sharp edges (87 to 88°) grip where dull edges (90°) slide. On rails, sharp edges catch dangerously while dull edges slide smoothly.
What Is Base Edge Angle?
Base edge angle is a slight bevel on the bottom of the edge that controls how easily the board tips onto its edge to start a turn. A 0° base edge means the edge is flush with the base. A 1° base edge means the edge is angled 1° away from the snow when the board is flat. This tiny bevel makes turn initiation easier because the board does not catch when flat on the snow. More base edge (1°) means easier turn entry but slightly less maximum edge hold. Less (0°) means more grip but stiffer turn initiation.
How to Tune Snowboard Edges: Tools and Method
You need an edge guide (file guide), a diamond stone or file, and a base edge guide. Total cost: 30 to 60 USD for a basic kit.
Side edge: set edge guide to desired angle (87°, 88°, 89°). Clamp to the board edge. Draw diamond stone or file along the edge, tip to tail, 5 to 10 passes. Check sharpness: a sharp edge catches your fingernail when dragged across it at 45°.
Base edge: set base edge guide to desired angle (0°, 0.5°, 1°). Place board base-up. Draw file along the base edge, 3 to 5 passes. Very little material removal needed.
Detuning: run a gummy stone along tip and tail contact points to round them slightly.
Finishing: remove burrs with a gummy stone. Wipe edge with a clean cloth.
Detuning: Why and Where
Detuning means intentionally dulling specific sections of the edge to prevent catching, especially at the tip and tail contact points. The contact points are where the edge first touches the snow as the board flexes. Sharp contact points catch in soft snow or during nose or tail maneuvers. Detune the first and last 5 to 10 cm of each edge for freestyle, 3 to 5 cm for all-mountain. NEVER detune the effective edge under the bindings (where you actually turn).
Edge Angles for Icy Conditions
If you regularly ride icy or hard-pack snow (East Coast, late season, early mornings), go 1° sharper than your standard style recommendation. Ice demands more edge. An all-mountain rider who normally uses 88° should try 87° for ice days. The trade-off: sharper edges catch more on soft snow and are less forgiving. If you ride both ice and powder, tune for ice and detune tip and tail for powder forgiveness. Alternatively, own two boards with different tunes.
Frequently asked questions
What edge angle for snowboard all-mountain?
88° side edge with 0.5° base edge. This balances grip on groomed runs with forgiveness on variable terrain. If you ride primarily ice or hardpack, try 87°. If you prefer more forgiveness, try 89°. Adjust 1° at a time.
Should I detune my snowboard edges?
Yes, the tip and tail contact points (first and last 5 to 10 cm). This prevents catching during flat-base maneuvers. Freestyle riders should aggressively detune tips and tails. All-mountain riders should lightly detune tips only. Carvers should NOT detune. Never detune the effective edge under the bindings.
How often should I sharpen snowboard edges?
Every 4 to 6 full days of riding for all-mountain. Every 3 to 5 days for carving on hardpack (aggressive riding dulls edges faster). Every 5 to 10 days for freestyle (park riding naturally dulls edges, which is desirable). Quick touch-up with a diamond stone takes 5 minutes. Full tune with a file guide takes 15 to 20 minutes.
What is the difference between 87° and 90° edge angle?
87° is sharp (aggressive grip, catches in soft snow, best for ice and carving). 90° is flat or dull (no grip on ice, slides freely on features, best for park and rails). Each degree makes a noticeable difference. 88° is the most popular all-round angle. Start there and adjust 1° based on preference.
