How Much Rope Fits in Your Arborist Bag? A Quick Guide

When choosing the right rope bag for arborist work, getting the right size makes all the difference — too small and you’ll struggle to pack your line, too large and you’re carrying unnecessary bulk. Here’s a quick reference based on common rope sizes and our popular bag options from Stein.

• Stein Vault 15 (15L) – comfortably holds around 45m of 11.7mm diameter rope, so works will with 10mm diameter rope up to 50m.

• Vault 30 (30L) – ideal for 100m of climbing rope, with space for a little extra gear if needed.

• Stein Voyager 50 (50L) – great for up to 200m of 12mm diameter rope, depending on how tightly it’s packed.

• Stein Voyager 60 (60L) – the safest choice for 200m lengths of 12mm rope if you prefer a bit of room to spare or carry additional kit.

So, whether you’re packing for a light climb or a full day of rigging, these rough guides should help you pick the right bag for the job.

Tip: When in doubt, size up — it’s always easier to carry a bit more space than to repack on site!
