Short answer
Meranti is a hardwood in botanical terms, but in practical terms it is a medium-density wood, harder than most common softwoods and softer than woods such as oak or teak. The commonly cited Janka hardness figure for dark red meranti is about 800 lbf, though the name covers a group of species, so values vary.
Hardwood label versus actual hardness
“Hardwood” and “softwood” describe the type of tree (broadleaf versus conifer), not how hard the wood is. Meranti comes from broadleaf trees, so it is a hardwood. Janka hardness measures the force needed to push a steel ball partway into the wood and is a better guide for dents and wear. Meranti sits in the middle: tougher than many pines, but easily dented compared with dense hardwoods.
How meranti compares
- Pine: Many common pines are softer and lighter, though some species such as southern yellow pine are not far off. Meranti is often more dimensionally stable and has a finer finish.
- Mahogany: Meranti is often sold as Philippine mahogany or lauan, but it is not related to true mahogany (Swietenia or Khaya). True mahogany generally has a finer, more consistent appearance and often better working qualities. Which is “better” depends on use, budget and availability.
- Oak and teak: Both are generally harder and heavier. Compare them in indoor teak furniture care and is sal wood good for furniture for denser alternatives.
Meranti groups vary
Meranti is a trade name for several Shorea species, generally grouped as light red, dark red, white and yellow meranti, plus the much denser balau. Strength, colour and durability differ between groups, so ask the supplier which type you are buying.
Working properties
Meranti is generally easy to work with hand and power tools, and takes glue, stain and finish well. Interlocked grain can cause tear-out when planing, and some species contain small amounts of silica that can dull cutters over time. Wood with resin streaks may need cleaning before finishing. It is not well suited to steam bending.
Downsides of meranti
- It dents more easily than dense hardwoods.
- Durability is reported as moderate to poor in some groups, and it can be vulnerable to insects.
- Quality and consistency vary widely.
- It is not a premium look for some buyers.
- Sustainability concerns exist for some Shorea species.
Is meranti a cheap wood?
It is generally treated as a moderately priced timber and is widely available, but prices vary with grade, region and supply, so compare current quotes.
Indoor and outdoor use
Meranti is common in interior furniture, joinery, doors, windows and plywood (see furniture plywood types). Some suppliers sell it for exterior joinery, but it needs a good protective coating and maintenance (see the best clear finish for an exterior door). Wood stays sound when it stays dry. For outdoor furniture and finishing, see eucalyptus furniture care and sealing for general finish principles.
Sourcing and sustainability
Many Shorea species are listed as threatened on the IUCN Red List. Look for timber from certified, legally verified sources, and ask suppliers for documentation.
Safety when working meranti
Dust from Shorea species has been reported to cause eye, throat and skin irritation, and severe reactions are uncommon. Wear a fitted respirator and eye protection, use dust extraction, and wash up after sanding. Use sharp blades, keep guards in place, secure the workpiece and never force a cut. Ventilate when applying finishes and keep rags that contain drying oils away from heat, laid flat outdoors or sealed in water.
