Two scales, no single standard: how to read the Schall and Hüsler grading systems correctly and find the via ferrata that matches your level.
There is no single, globally standardised via ferrata scale — in the Alps, two systems dominate: the letter scale A to E/F by Kurt Schall (mainly Austria) and the number scale K1 to K6 by Eugen Hüsler (mainly Switzerland). Sounds confusing, but it is quick to learn — and crucial to making your next tour a success story instead of a blockage that ends with mountain rescue.
The honest rule of thumb for beginners, in case you missed it in the first guide of this series: A or K1/K2. Anything above that already demands noticeable arm strength and climbing experience you should build up first.
### 1. Understand the Schall scale (A–E) A means easy, well-secured paths with short exposed sections; B means steeper, rockier terrain; C means steep to very steep terrain with small footholds; D means vertical, often overhanging terrain with widely spaced rungs — here you already need noticeable arm strength; E is practically continuously overhanging and only for very experienced via ferrata specialists.
### 2. Understand the Hüsler scale (K1–K6) K1 roughly matches a well-secured, wide path with steps; K2 has the first short, protected steep steps; K3 partly runs through steep, exposed rock; K4 becomes vertical with short overhangs and smaller footholds; K5 is long, strength-sapping and steep to slightly overhanging; K6 is practically just steel cable with no rungs, extremely demanding.
### 3. Remember scales stay imprecise Even between guidebooks, the same route can differ by half a grade — scales are orientation, not a contract. Also read length, elevation gain and approach time, not just the letter or number.
### 4. Progress in small steps Do several A/B tours before switching to C. The jump from B to C is noticeably bigger than from A to B, because this is the first time real arm strength is required.
Being overwhelmed by a route chosen too hard is, per DAV analysis, the most common trigger for via ferrata rescue call-outs — more than half of all reported cases are "blockages", where people are unhurt but overwhelmed and can go neither forward nor back. When in doubt, pick the easier option — a via ferrata is not going anywhere, and it will still be there next year.
Also keep in mind: the grade describes technical difficulty, not the psychological load of exposure. Some people handle C technically with ease but get unsettled on exposed B sections with a long drop below — that is a completely different factor from pure climbing difficulty.
After every tour, note how the grade actually felt compared to the guidebook rating. After three or four tours you develop a feel for whether you are "hard at the bottom" or "comfortably at the top" of your current level — that is more precise than any scale. Keep these notes as a short list on your phone; it will still help with tour planning years later.
### Which grade is suitable for absolute beginners? A or K1, ideally on a short tour with good access. Only once that feels safe and relaxed do you move up a grade.
### Are the Schall and Hüsler scales directly comparable? Roughly yes: A matches roughly K1, B roughly K2, and so on — but the conversion is not exact, because both scales weight different criteria. Rely on the detailed description rather than a pure letter-number conversion.
### How quickly can I progress? It depends on fitness and frequency, but realistically most beginners need several tours per grade before the next step feels safe rather than risky. Better to progress slowly than skip a grade.
### What if I realise mid-tour that it is too hard? Turn back as soon as the option arises — many routes have emergency exits. Retreat is not a disgrace, it is the right decision before a blockage or a fall develops from it.
### For group tours, does the route grade matter or my own level? Always your own level. A group is only as strong as its weakest member — plan the tour around the least experienced person, not the average or the strongest climbers.
