The 5 Best Beard Trimmers for Long Beards
So your beard is past the stubble stage, and every trimmer you find promises dozens of settings. The number that matters is the longest guard. A ten-millimeter ceiling will quietly take off the bulk you wanted to keep. I would measure the beard where it is fullest before choosing a kit, then leave room above that length for a cautious first pass. A trimmer can neaten a long beard; it cannot put back a half-inch cut by the wrong comb.
My first pick is the Panasonic ER-GB96 because its specified 30 mm range makes sense for a genuinely long beard. The Beard Club PT45 reaches about 27 mm and gives you separate guards; Philips Norelco 5500 is a simpler 20 mm choice. Braun's Series 9 kit earns its place if you also cut hair or tidy other areas. King C. Gillette is the inexpensive 20 mm option. The right buy depends on your actual length, whether you want a dial or separate combs, and how much kit you are willing to keep clean.

01 — Panasonic
Best overall for a long beardPanasonic ER-GB96
The ER-GB96 is the pick I would start with for a beard that has grown well beyond stubble. Panasonic specifies a 1–30 mm range, so its longest setting can preserve more bulk than the common 10 or 20 mm trimmers. It has 58 length steps and a comb designed for longer hair. That range is the useful feature here; the setting count alone is not a reason to buy. Check that the exact attachment is included and brush out trapped hair as the maker directs.
It ranks first because the verified 30 mm ceiling fits the guide's core buyer without asking them to freehand an even cut. The less expensive PT45 comes close at about 27 mm; the 20 mm models below are better for shorter long-beard styles or other grooming jobs.

What to weigh
−Costs more than the 20 mm alternatives.
- Maximum guarded length

02 — The Beard Club
Best separate-guard alternativeThe Beard Club PT45
The PT45 gives you eight color-coded guards through 25 mm, with blade adjustment that takes the maker's stated cutting range to about 27 mm. Separate guards make the chosen length obvious once you learn the colors, and the long ones are genuinely useful for keeping a full beard. The trade-off is storage and upkeep: this trimmer is not waterproof, and The Beard Club calls for brushing and periodic blade oiling. I would keep the guards together rather than relying on memory.
Second place reflects a meaningful long-beard reach at a lower current offer than Panasonic. I would move it above Panasonic if you prefer physical guards; I would keep Panasonic first when 30 mm and one adjustable system matter more.

- Brush and oil blade; trimmer is not waterproof
03 — Norelco
Best straightforward 20 mm trimmerPhilips Norelco Beardtrimmer 5500
Philips Norelco's Series 5500 reaches 20 mm, which is enough for a controlled medium-to-long beard but not for keeping an inch of guarded length. Its adjustable wheel is easier to revisit than a loose-guard kit if you return to the same setting every week. I would choose it when my beard sits comfortably below its ceiling and I do not want extra grooming heads. If the beard is already longer, start with scissors or choose one of the longer-range models above.
It sits third because 20 mm is a real, documented range, yet it leaves less headroom than Panasonic or PT45. For someone maintaining a beard closer to 15 mm, this simpler format could be the best buy in the list.

+Clear 20 mm adjustment range.
What to weigh
−Cannot preserve longer bulk with its comb.
- Maximum guarded length
- 20 mm
- Model
- Series 5500 BT5511
04 — Braun
Best for beard plus other groomingBraun All-in-One Series 9 AIO9535
Braun's AIO9535 is a full grooming kit, and its longer precision comb covers the 10.5–20 mm range. That gives it a place for someone who wants beard upkeep and hair or body attachments in one case. I would buy it for those extra jobs, not because an all-in-one label promises a longer beard cut. Check the included combs against the exact listing and keep body-use attachments separate and clean.
Fourth place is intentional: the extra heads broaden its uses, while the 20 mm limit makes it less compelling for a beard-focused buyer than the first three. It moves up if replacing several grooming tools is the real goal.

+Multi-area grooming in one kit.

05 — Gillette
Best budget 20 mm optionKing C. Gillette Beard Trimmer PRO
King C. Gillette's PRO has two adjustable combs spanning about 0.5–20 mm in 0.5 mm steps. At its current offer, it is the affordable route to a genuinely stated 20 mm setting. It is a sensible choice if your beard is full but not longer than that limit and you mainly want to keep its outline tidy. I would set the comb longer than planned on the first pass; a cheap trimmer is no bargain if its top guard cuts too much.
Fifth place reflects the shortest long-beard ceiling in this group, shared with Philips and Braun, and a more basic package. It becomes the most sensible pick when the 20 mm range is enough and price matters more than a 27–30 mm reserve.

FAQ — Beard Trimmers for Long Beards
01What maximum guard length do I need for a long beard?+
Measure the beard you want to retain. The Panasonic reaches 30 mm, the PT45 about 27 mm, and the Philips, Braun and King C. Gillette options top out around 20 mm. Choose a guard longer than your target length for the first pass.
02Can I use a beard trimmer on hair longer than its highest guard?+
You can freehand the shape or use scissors and a comb, but the trimmer cannot give a repeatable guarded cut beyond its stated range. For a beard longer than 30 mm, keep scissors or a barber in the routine.
The short answer
Start with the Panasonic ER-GB96.
I recommend it for someone keeping a beard around 20–30 mm with repeatable guarded trims. Choose something else if you only keep a short beard and do not need the premium long-range comb.
