Choose a wooden wick when you want a wider flame, a gentle crackle, and a stronger melt pool across the whole candle. Choose a hemp wick when you want a plant-based wick that burns slower and cooler with minimal fuss. Safety comes down to correct sizing and consistent care rather than the material itself, and we make wooden-wick candles with that testing built in from the start.
TL;DR:
- Judge a candle’s scent only after the melt pool reaches the container’s edge; tunneling, soot, or weak fragrance can signal poor sizing or care.
- Trim either wick to 5 to 7 millimeters before each burn, limit sessions to about 4 hours, and stop with 12.7 millimeters of wax remaining.
- Snap off a wooden wick’s charred tip after every burn before relighting, since leftover char can prevent a clean, reliable reignition.
- Makers should test small batches after the wax cures, adjusting wick size incrementally to match the wax and vessel width.
- Do not substitute plain hemp string for a candle wick; proper hemp candle wicks are braided and usually beeswax coated for an even burn.

What Wooden Wicks and Hemp Wicks Are Made Of
A wooden wick is exactly what it sounds like: a thin strip or veneer of wood, sometimes a single ply and sometimes layered with a second material for stability. According to the National Candle Association, wooden wicks come in several forms, including single-ply, multi-layered, curved, and decorative shaped versions, each chosen for a slightly different look or burn style. The wood’s density and shape decide how wide the flame spreads and whether you hear that soft, recognizable crackle as it burns.
A hemp wick is built differently. It’s braided from hemp fibers, often coated in beeswax to help it hold a flame evenly, and it produces a narrower, more upright flame than wood. Where a wooden wick spreads heat sideways, a braided hemp wick concentrates it in a tighter column.
These construction differences carry real consequences for how a candle performs:
- Wooden wicks create a wider, horizontal flame that warms more wax surface at once, which is part of why they’re linked to a faster, fuller melt pool.
- Hemp wicks burn cooler and more slowly, which suits waxes and fragrance blends that don’t need intense heat to release their scent.
- Material thickness and coating (wax-dipped hemp versus bare wood) change how quickly either wick ignites and how much trimming it needs between burns.
Neither structure is automatically “better.” They’re built for different burning styles, and that’s the real starting point for choosing one.
How Each Wick Burns: Flame, Melt Pool, and Scent
Flame shape is the clearest giveaway. A wooden wick burns wide and low, almost like a small hearth fire, while a hemp wick burns tall and narrow, closer to what you’d expect from a traditional cotton wick. That shape difference changes melt pool speed: the wider wood flame tends to liquefy wax faster across the surface, while a hemp wick needs more time, and sometimes a larger wick size, to reach the edges of the container.
Scent throw follows the same logic. A faster, hotter melt pool releases fragrance oils more quickly, which is why wood-wick candles often feel more fragrant early in a burn. Hemp’s cooler flame releases scent more gradually, which some people prefer for a softer background fragrance rather than a strong first impression.
On any first burn, watch for a few warning signs:
- Tunneling, where wax melts only in the center and leaves solid wax around the edges.
- Visible soot building up on the inside of the glass or on the wick itself.
- Weak or absent scent throw even after the wax has fully melted across the surface.
Pro Tip: Judge scent throw only after the first full melt pool reaches the edge of the container. Smelling it too early will underestimate how fragrant the candle actually is.
Trimming, Burn Limits, and Safety Standards to Follow
Safety rules are nearly identical for both wick types, and they matter more than any marketing claim about which material is “safer.” Health Canada’s candle safety guidance recommends a short, repeatable routine:
- Trim the wick to 5 to 7 millimeters (about 1/4 inch) before every light, which keeps the flame controlled and prevents excess soot.
- Limit each burn session to about 4 hours, since longer burns raise the risk of container overheating.
- Stop burning once about 12.7 millimeters (1/2 inch) of wax remains, as the flame can get too close to the container bottom after that point.
Wooden wicks need one extra step: snap off the charred tip after each burn before relighting, since leftover char can block a clean reignite. Our own first-burn and trimming guide walks through that process in more detail.
A properly sized wick, not the wick material, is the main factor separating a safe burn from a risky one, according to Health Canada’s guidance. That’s why candle makers lean on standardized testing rather than guesswork. ASTM F2417 lays out test methods for flame height, container integrity, and wick migration, the same checks professional candle makers run before releasing a new wick-and-wax pairing. If you’re testing at home, burn away from drafts, watch for a container that feels too hot to touch, and note any soot forming on the inner glass. Those are the same practical red flags the standards are built to catch.
A Quick Decision Checklist for Makers and Buyers
If you’re making candles, start with your wax type and vessel width, since both determine which wick size will actually reach full melt pool. Run small test batches, let each one cure fully, and adjust wick size incrementally rather than guessing at the final version.
If you’re buying rather than making, the choice is simpler:
- Pick a wooden wick if you want the crackle, the wider flame, and a melt pool that reaches the glass edges reliably.
- Pick a hemp wick if you prefer a plant-based wick with a cooler, quieter burn and don’t mind a slower melt pool.
- Watch for tunneling or weak scent as your cue to re-trim, retest with a different wick size, or switch wick types entirely.
Small adjustments, like moving up one wick size or giving a new batch a longer cure time, often solve a problem before you need to abandon a wax or fragrance blend you otherwise like.
Why We Trust Wooden Wicks for Our Candles
We built our candles around coconut soy wax and wooden wicks because that pairing gives us the clean burn and steady melt pool we want for every fragrance we offer. A few things back up that choice:
- We use biodegradable packaging and vegan ingredients in our candle line.
- Every candle purchase helps support women and children escaping crisis.
- Our approach to clean-burning candles has received very positive customer feedback.
- Our wooden wick safety guide and wood wick care post cover FSC certification, trimming, and troubleshooting in plain language, so you’re never guessing at the right technique.
That combination, clean ingredients, sturdy care resources, and a cause behind every purchase, is what we lead with instead of vague claims.
Cost and Availability: What to Expect From Each Wick
Wooden wicks tend to cost a bit more per unit than hemp, largely because the veneer cutting and multi-ply construction take more processing than braiding hemp fiber. That said, the price difference per candle is small once you account for how few wicks a single candle needs.
Availability differs more than price does. Wooden wicks are widely sold at craft retailers and specialty wax suppliers, often in bundles with pre-attached sustainers, making them simple to source for small-batch makers. Hemp wicks are also common, frequently sold in bulk spools since they’re used outside candle making too, including in lighters and rolling papers, which keeps supply steady but means you may need to cut and treat them yourself for candle use.
For everyday buyers, cost and availability come down to the finished candle rather than the raw wick. Our Non-Toxic Candles collection runs $21 to $31 per candle, and our Non-Toxic Wax Melts are priced at $12, both using the same coconut soy wax and wooden-wick construction regardless of fragrance.
Which Wick Is More Sustainable?
Both wood and hemp are renewable materials, but they get there differently. Wood wicks used in candle making are generally sourced from FSC-certified suppliers, meaning the wood comes from forests managed for long-term regrowth rather than clear-cutting. Hemp, for its part, grows quickly with relatively few pesticides and inputs, which is part of why it shows up across other product categories too, including breathable, natural fiber clothing where its fast growth cycle and biodegradability are frequently highlighted.
Neither wick leaves meaningful waste behind. Wood burns down to ash, and untreated hemp fiber breaks down the same way. The bigger sustainability factor is usually what surrounds the wick, the wax, the container, and the packaging, rather than the wick itself. That’s why we pair our wooden wicks with coconut soy wax and biodegradable packaging rather than treating the wick as the only sustainability decision worth making.
A Maker’s Quick Take
If you want one flame style to default to, choose wood for the crackle and the fuller melt pool, and reach for hemp when a cooler, quieter burn suits the project better. Either way, trim before every light, test a few sizes, and follow the standards instead of assumptions.

FAQ
Are wood wick candles better than other types?
Wood wick candles aren’t universally better, but they do offer a wider flame, a soft crackling sound, and often a stronger melt pool when properly sized. Whether one suits you depends on whether you want that crackle and broader heat, or a quieter, cooler burn instead.
Can I use hemp string as a candle wick?
Plain hemp string isn’t built the same way as a proper hemp candle wick, which is braided and typically coated in beeswax to burn evenly. Untreated string can burn unpredictably, so it’s safer to use a wick made specifically for candles.
What is the point of a hemp wick?
A hemp wick gives you a plant-based, slower-burning option that produces a cooler flame with minimal crackle. It’s a straightforward choice for makers who want a lower-heat burn or a more understated flame style.
What are the best wooden candle wicks to look for?
The best wooden wicks are ones properly sized to your wax and container, since sizing affects melt pool and safety more than the wick style itself. Look for FSC-certified wood and test a couple of sizes, as recommended in National Candle Association guidance, before settling on one for a full batch.
