Fire Blankets
Fire Blanket Sizes Compared
A size chart built from real listings rather than a generic table — and the one dimension that decides whether a blanket can do more than cover a pan.
By Ryder M.Last reviewed
The practical dividing line is about 47 inches. Everything below it — the 36 x 36 in Waylander, the 39 x 39 in Prepared Hero and the 40 x 40 in JJ CARE blankets — is a hob blanket: enough to cover a pan or a small appliance fire, not enough to wrap around an adult. At 47.2 x 47.2 in the Tonyko is the smallest blanket on this site that can serve as a body heat shield as well, and Tonyko also sells 47.2 x 70.9 in and 78.7 x 78.7 in versions of the same product. If you are buying one blanket for a kitchen, 39 to 40 inches is adequate. If you want one blanket that covers both jobs, buy at least 47 inches and check which size you are actually putting in the basket.

Fire blanket size chart, from real listings
Every dimension is the manufacturer's or seller's published figure for the product linked on this page. There is no generic row in this table.
| Blanket | Published size | Material | Covers a pan? | Body heat shield? | Standard named |
|---|---|---|---|---|---|
| Waylander Carbon Felt | 36 x 36 in (cuttable) | Carbon felt, rated to 1800°F | Small pans only — not a cooking blanket | No | None — explicitly not EN 1869 |
| Prepared Hero | 39 x 39 in | Woven fiberglass with a fire-retardant inner layer | Yes, with margin | No | CE conformity, EN 1896:1997 named |
| JJ CARE | 40 x 40 in (two in the kit) | Dual-layer woven fiberglass | Yes, with margin | No | None named |
| Tonyko | 47.2 x 47.2 in (also 47.2 x 70.9 and 78.7 x 78.7) | Woven fiberglass | Yes, easily | Yes | EN 1869:1997 named |
Sizes are as published and can change without a model number changing. Measure your hob and check the size on the listing before you order.
What each size can physically do
Up to about 40 inches — the hob blanket. This is the size nearly every domestic fire blanket is sold in, and it is sized for the job it is bought for: a pan on a hob, a toaster, a small appliance, a wastebasket. Lay it over, hold the edges down, cut the air off, turn the heat off, and leave it in place until everything is cold. Cooking is the leading cause of home fires, which is why this is the size that matters most.
About 47 inches — the dual-purpose blanket. At this size the blanket covers a hob fire with room to spare and becomes large enough to wrap around an adult as a heat shield while they move away from a fire. That second use is not a rescue technique for carrying somebody out; it is protection for a short movement past heat.
Above 47 inches — the specific-purpose blanket. The 47 x 71 in and 78 x 78 in versions exist for a reason: a larger appliance, a vehicle, a grill, a wood stove surround, a work area. They are harder to store, slower to deploy and better at covering a large object. Buy one as an addition to a kitchen blanket rather than instead of it.
And smaller than 36 inches is not a fire blanket. The small squares sold in car kits and novelty sets do not cover a pan with the margin you need to hold the edges down. If a blanket cannot be held down at its edges while it covers the fire, air gets in and the fire stays lit.

The four blankets, by size
1. One blanket that covers both jobs — 47.2 x 47.2 in
Tonyko Fiberglass Fire Blanket
The smallest size here that works as a body heat shield as well as a pan cover, and the only brand naming an EN 1869 edition.
- Listed to
- Tonyko states the blanket meets EN 1869:1997 for cooking-fire suppression
- Sensing / agent
- Woven fiberglass
- Power / service life
- Single use on a real fire
Why 47 inches is the line. A pan fire needs a blanket wide enough to cover the pan plus enough margin to hold the edges down and smother the air supply, which a 39 in square does comfortably. Wrapping a person is a different dimensional problem: you need enough material to cover from shoulder to knee and overlap, which a 39 in square does not give you. Forty-seven inches is where one blanket starts to do both.
What the EN 1869 reference buys you. There is no US standard for a domestic fire blanket, so the European cooking-fire blanket specification is the only named standard anybody in this category cites. Tonyko names a specific edition. Prepared Hero names CE conformity and EN 1896:1997. JJ CARE names nothing at all. In a category with no mandatory testing, naming a standard and its edition is the clearest signal available — and it is still a seller claim, not a certification mark.
Plan the fixing when you order. This is a bare blanket. A fire blanket in a drawer is a blanket somebody has to open a drawer to get, which is one movement too many, and a blanket on a hook two feet from the hob is the one that gets used. Buy a hook, and read where to mount a fire blanket before you pick the spot.
What it does well
- **47.2 x 47.2 in (1.2 x 1.2 m) — large enough to wrap around a body as a heat shield**, which the smaller hob blankets are not
- **Tonyko names a specific EN 1869 edition (1997)**, which is more than most sellers in this category do
- Also sold in 47.2 x 70.9 in and 78.7 x 78.7 in, so the same product scales up if you want a larger one
- Tonyko names the kitchen, fireplace, grill, car and camping as the intended uses — the range a larger blanket actually makes possible
- Woven fiberglass, the conventional and well-understood construction for a cooking-fire blanket
The downside
- **Plain blanket — no pouch and no hooks in the pack**, so you have to plan the fixing yourself
- **Check which size you are adding to the basket.** Three sizes share one listing family and the price differences are easy to misread
- Woven fiberglass, so the fiber question applies: handle the edges with care and use gloves if you have them
- Single use on a real fire — inspect and replace after any deployment
- A 47 in blanket is bulkier to store than a 39 in one, which matters in a small kitchen
Do not buy this if: a drawer next to the hob where only a small folded square will fit. In that case buy a 39 or 40 inch blanket and keep it where you can actually reach it — a blanket in reach beats a bigger blanket in the hall cupboard.
- Tonyko names a specific EN 1869 edition, which is more than most sellers in this category do

2. The best-equipped hob blanket — 40 x 40 in, with gloves
JJ CARE Fire Blanket Kit
Two blankets, gloves and hooks in one box. Hob-sized, honestly described, and the gloves are the part people regret skipping.
- Listed to
- JJ CARE does not name a listing number or test standard on its listing
- Sensing / agent
- Dual-layer woven fiberglass
- Power / service life
- Single use on a real fire; JJ CARE states the blankets themselves do not expire in storage
The size here is honest and the kit is the reason to buy it. Two blankets means the kitchen and one other hazard get covered for one price, and the gloves genuinely change what you can do: a fiberglass blanket conducts heat, and holding one down over a burning pan with bare hands is the point at which people let go.
The adhesive hooks are the weak part. They hold on smooth gloss paint and fail on textured plaster, tile grout lines and anything greasy — which describes most kitchen walls near a hob. Spend two minutes putting a screw in instead.
Best fire blankets for kitchens is the full kitchen roundup.
What it does well
- **Ships as a kit: two 40 x 40 in blankets, protective gloves and adhesive hooks** — the kitchen and the garage covered in one purchase
- **Gloves are the part people skip and then regret**, because a blanket transmits heat and you are holding it over flames
- Sold in pack sizes from two upwards, so a second blanket can go in the garage or the car
- Dual-layer woven fiberglass, the conventional construction
- JJ CARE states the blankets themselves do not expire in storage
The downside
- **JJ CARE does not name a listing number or test standard on its listing** — nothing to check at all
- **40 x 40 in is hob-sized — enough for a pan, not enough to wrap an adult**
- **Adhesive hooks fail on textured walls**; use a screw fixing if you can
- Woven fiberglass, so the fiber question applies
- Single use on a real fire
Do not buy this if: a buyer who wants a named standard to check. If documentation matters more than the kit contents, buy the Tonyko and a pair of gloves separately.

3. The easiest to deploy — 39 x 39 in, pull-tabs and a sleeve
Prepared Hero Emergency Fire Blanket
39 x 39 in with pull-down tabs and a hanging slot. Hob-sized, and the deployment mechanism is the best here.
- Listed to
- Prepared Hero states conformity to CE safety standards, naming EN 1896:1997
- Sensing / agent
- Two layers of woven fiberglass around an inner fire-retardant layer
- Power / service life
- Single use on a real fire; inspect and replace after any deployment
The deployment mechanism is what this size does best. You will reach for a blanket while looking at a fire, not at the wall, and a sleeve with two pull tabs comes out in one motion. A folded square on a shelf has to be found, unfolded and oriented.
On size: 39 inches covers a large frying pan with real margin and will smother a wastebasket or a toaster. What it will not do is wrap a person, and no amount of technique changes the dimensions. Fire blanket vs fire extinguisher covers which tool suits which fire.
Prepared Hero vs alternatives is the brand-level comparison.
What it does well
- **Pull-down tabs deploy it, which is the only mechanism that matters when you are reaching blind** at a wall beside a burning pan
- **A hanging slot in the sleeve**, so it can live on the wall rather than in a drawer
- 39 x 39 in, sold as a two-pack so a kitchen and a garage can both be covered
- Prepared Hero states conformity to CE safety standards, naming EN 1896:1997
- No powder, no residue, no clean-up beyond throwing the blanket away
The downside
- **39 x 39 in is hob-sized** — a pan, a small appliance, a bin. Not a person
- Woven fiberglass around a fire-retardant inner layer, so the fiber question applies to it
- Single use on a real fire; inspect and replace after any deployment
- The standard it names is a CE conformity claim rather than a US certification
Do not buy this if: somebody who wants one blanket to double as a body heat shield. At 39 inches it cannot, and the 47 in Tonyko is the smallest here that can.
- 39 x 39 in, sold as a two-pack so a kitchen and a garage can both be covered
- Pull-down tabs deploy it, which is the only mechanism that matters when you are reaching blind
- No powder, no residue, no clean-up beyond throwing the blanket away
- Woven fiberglass construction, so the fiber question below applies to it
- A hanging slot in the sleeve, so it can live on the wall rather than in a drawer

4. The smallest — 36 x 36 in, and not a kitchen blanket
Waylander Carbon Felt Welding Blanket (36 x 36 in)
Carbon felt rated to 1800°F, made in the USA, cuttable. A welding blanket, which is a different product with a different job.
- Listed to
- An industrial welding blanket. It is NOT certified to EN 1869, the cooking-fire blanket standard, and is not intended for pan fires
- Sensing / agent
- Carbon felt, rated by the manufacturer to 1800°F
- Power / service life
- Reusable for spark and slag protection; discard after any real fire deployment
This belongs on a size comparison for two reasons. It is the smallest blanket on this site, and it is the only one whose size you can change: carbon felt cuts cleanly without unraveling, so a 36 in square becomes whatever shape a hearth or a bench needs.
It is also the one blanket here that is not a cooking-fire product, and we are not going to blur that. Waylander sells it for welding and spark protection. It is not certified to EN 1869, nobody has tested it against a pan of burning oil, and its reusable rating applies to slag and sparks rather than to a fire. Buy it for a workshop, a wood stove surround or a fiberglass-free requirement.
Fiberglass-free fire blankets and are fire blankets toxic both go into the material question properly.
What it does well
- **Carbon felt rather than woven fiberglass, so it sheds no glass fiber** — the material answer for anybody avoiding fiberglass
- **1800°F rating — far above the woven fiberglass blankets sold for kitchens**
- **Explicitly Made in USA**, which almost nothing else in this category is
- 36 x 36 in, and **it can be cut to size without unraveling** — the only blanket here where the size is adjustable
- Reusable for spark and slag protection rather than single-use
The downside
- **It is an industrial welding blanket. It is NOT certified to EN 1869, the cooking-fire blanket standard, and is not intended for pan fires**
- 36 x 36 in is the smallest here — below the useful size for a large pan with margin
- Sold for welding, glass blowing, auto body work and wood stoves, not marketed as a kitchen blanket
- No pouch, no hooks, no pull tabs — nothing that makes blind deployment quick
- Discard after any real fire deployment despite the reusable spark rating
Do not buy this if: your kitchen fire blanket. We include it because the size chart would be dishonest without it and because it is the right answer to a different question — fiberglass-free material for a workshop or a wood stove hearth.
- Explicitly Made in USA, which almost nothing else in this category is
- Carbon felt rather than woven fiberglass, so it sheds no glass fiber
- 1800°F rating — far above the woven fiberglass blankets sold for kitchens
- 36 x 36 in, and it can be cut to size without unravelling
- Sold for welding, glass blowing, auto body work and wood stoves — not marketed as a kitchen blanket

What size to buy for each job
Six situations and the size that suits each. Where this site has a dedicated page, it is linked.
- A kitchen hob. 39 to 40 in, with a sleeve or hooks, mounted within arm's reach but not directly over the hob. Best fire blankets for kitchens.
- One blanket for the whole house. 47 in, so it covers a pan and can serve as a heat shield. What size fire blanket do I need is the decision guide behind this chart.
- A car or an RV. 39 to 40 in in a sleeve that lives in the glovebox or a door pocket — small enough to store, big enough for an engine-bay or interior fire. Best fire blankets for cars and for RVs.
- A grill or a fire pit. 47 in or larger, because the object is bigger than a pan and the blanket has to cover it and reach the ground. Best fire blankets for grills.
- A lithium battery charging station. Size is almost beside the point here — read the limits in best fire blankets for lithium batteries before you rely on any blanket for a pack in runaway.
- A workshop bench or a wood stove hearth. Carbon felt, cut to the shape of the area. This is the Waylander's actual job. Fiberglass-free fire blankets.
Two things the size chart does not tell you
Material matters as much as dimensions. Three of these four blankets are woven fiberglass, which is the conventional material and the reason people ask about splinters and skin irritation. Occupational health guidance on synthetic vitreous fibers is about repeated industrial exposure rather than one emergency use, and a fire blanket deployed once in a kitchen is a very different exposure from a working life in insulation. But if that is a concern in your household, carbon felt is the alternative and it is a real one. Are fire blankets toxic covers what the evidence actually says.
And reach beats size, every time. A 47 in blanket in a cupboard in the hall is worse than a 39 in blanket on a hook two feet from the hob. The deciding factor in whether a blanket works is whether somebody can get it in one movement while looking at a fire, which is why the pull-tab sleeve on the Prepared Hero and the hooks in the JJ CARE kit are features worth as much as an extra eight inches of cloth.
Then know how to use it, because a blanket used badly is worse than none: lay, do not throw; cover completely; hold the edges down; turn the heat off; leave it in place until cold; and do not lift it to check. How to use a fire blanket is a five-minute read that makes every size on this page work better.
