Key takeaways
- Mil-spec (MIL-C-5040H Type III): nylon sheath and nylon inner strands, each strand typically made of 3 twisted yarns. Rated strength is verified by the manufacturer. Usually $0.10 to $0.20 per foot.
- Commercial 550: often similar in appearance but may use polyester strands, 7 strands of thinner yarn, or a looser weave. Real breaking strength can be 300 to 450 lb. Usually $0.04 to $0.10 per foot.
The best paracord for survival is genuine Type III 550 paracord with 7 to 9 inner strands and a nylon sheath, ideally made to the MIL-C-5040H specification, because its inner strands can be pulled out for fishing line, sewing thread and snare wire while the full cord still holds a rated 550 lb. Lighter “commercial 550” sold cheaply often has fewer, thinner strands or polyester fillers and falls well short of that rating. For most camping and survival kits, 50 to 100 feet of true 550 cord is the sweet spot between weight and usefulness.
Paracord types: what the numbers mean
The “550” in 550 paracord refers to minimum breaking strength in pounds, not working load. Never use paracord for climbing, rappelling or lifting people; it is not life-safety rope.

View on Amazon| Type | Rated breaking strength | Inner strands | Diameter | Weight per 100 ft | Best use |
|---|---|---|---|---|---|
| Type I (micro-cord class) | 95 lb | Yarn core, no strands | ~1.8 mm | ~2 oz | Zipper pulls, lashing small items, lanyards |
| Type II | 400 lb | 4–7 | ~3 mm | ~4.5 oz | Lightweight guylines, ultralight kits |
| Type III (550) | 550 lb | 7–9 | ~4 mm | ~6.5 oz | General survival, shelters, bear bags, repairs |
| Type IV (750) | 750 lb | 11 | ~4.8 mm | ~9 oz | Heavier tarp ridgelines, hauling, tow-style tasks |
The weights above are typical for nylon cord and vary slightly by maker, but they show the trade-off: 750 cord is about 40% heavier for about 36% more strength. For a pack, 550 usually wins. For a vehicle kit or base camp, 750 is a reasonable choice.
Mil-spec vs commercial 550 paracord
- Mil-spec (MIL-C-5040H Type III): nylon sheath and nylon inner strands, each strand typically made of 3 twisted yarns. Rated strength is verified by the manufacturer. Usually $0.10 to $0.20 per foot.
- Commercial 550: often similar in appearance but may use polyester strands, 7 strands of thinner yarn, or a looser weave. Real breaking strength can be 300 to 450 lb. Usually $0.04 to $0.10 per foot.
Quick check at home: cut a 6-inch piece, pull out the inner strands and count them. Then unravel one strand: true Type III strands each have 3 smaller twisted yarns. Burn a sheath fiber: nylon melts and beads with a hard, dark tip, while polyester tends to drip and smell sweeter.
Atwood Rope MFG and Rothco are well-known US names for 550 cord, and Paracord Planet sells bulk spools in many colors. Atwood also makes specialty versions with reflective tracers.
Survival-enhanced cords
Some cords add extra inner strands designed for emergency use. Titan SurvivorCord, for example, keeps the standard nylon strands and adds fishing line, waxed jute (a fire tinder) and a strand of utility wire. The trade-offs:
- Slightly thicker and stiffer than plain 550, so knots are harder to tie and untie.
- Costs about two to three times as much per foot.
- Worth it for a dedicated survival kit or bracelet; overkill for everyday guylines.
How much paracord for camping and survival?
| Task | Typical length needed |
|---|---|
| Tarp ridgeline between two trees | 25–40 ft |
| Tarp guylines (4 corners) | 4 x 6–8 ft = 24–32 ft |
| Bear bag hang (PCT method) | 40–50 ft |
| Camp clothesline | 15–25 ft |
| Spare shoelaces, repairs, lashings | 10–15 ft |
| Total for a typical overnight kit | ~100 ft |
For a minimalist day-hike kit, 25 to 50 feet covers emergency shelter and repairs. A 100-foot hank of 550 weighs about 6.5 oz, a reasonable cost for the number of problems it solves.
Survival paracord bracelet: the real math
A bracelet is a convenient way to carry cord you would otherwise forget, but the amount is smaller than people expect. A cobra-weave bracelet uses roughly 1 foot of cord for each inch of finished length.
- 8-inch wrist, cobra weave: about 8 to 10 feet of cord.
- Wider “king cobra” double weave: about 15 to 20 feet.
Ten feet will lash a splint, replace a bootlace or rig a short guyline, but it will not pitch a tarp. Treat a bracelet as a backup, not your main supply. Pick one with a quick-release buckle or a “quick deploy” weave so you can unravel it in a minute rather than picking knots for 15.
Picks by situation
| Your situation | Choose | Length |
|---|---|---|
| Backpacking and camping | Mil-spec Type III 550, high-visibility color | 50–100 ft |
| Bug-out bag or vehicle kit | Survival-enhanced 550 or Type IV 750 | 100 ft |
| Ultralight thru-hiking | Type II or a dedicated Dyneema guyline | 30–50 ft |
| Everyday carry | Bracelet, keychain lanyard or knife handle wrap | 8–20 ft |
| Crafts and gear projects | Commercial 550 on a 1,000 ft spool | As needed |
Ownership realities
- Stretch: nylon paracord stretches around 30% before breaking. That is good for shock loads but bad for taut ridgelines; re-tension a tarp after an hour, especially when it gets wet.
- Abrasion: the sheath wears first where it rubs on bark or rock. Use tree-saver straps or a sacrificial wrap on rough trunks.
- UV: bright colors fade after a season of sun; faded cord loses some strength, so retire cord that has turned chalky or fuzzy.
- Cutting and sealing: melt cut ends with a lighter so the sheath does not fray. Use a hot knife on a spool for clean cuts.
- Color choice: orange, red or reflective cord is easy to spot at night and visible to searchers. Olive and coyote blend in, which is the opposite of what you want in an emergency.
