Bald cypress is generally harder and heavier than western red cedar, while western red cedar is lighter and valued for its stability. Both can work well outdoors, but neither is automatically the more durable choice in every situation.
Cypress usually has pale yellow to brown coloring. Western red cedar often has warmer reddish-brown tones, although both woods vary and can weather gray outdoors.
The names can also be confusing. “Cypress” and “cedar” describe several different woods with different properties. This guide mainly compares bald cypress (Taxodium distichum) with western red cedar (Thuja plicata), two common choices for exterior woodworking.
What Is Cypress Wood?
Bald cypress is a softwood native to the southeastern United States. Unlike many conifers, it sheds its needles seasonally.
Its lumber is used for siding, trim, paneling, furniture, and selected exterior applications. The wood generally has a straight grain and a light appearance that works with natural finishes or paint.
Cypress has a strong reputation for decay resistance, but much of that reputation comes from old-growth heartwood. Modern lumber can contain a different proportion of heartwood and sapwood and should not automatically be expected to perform identically.
Names such as Australian cypress, Monterey cypress, and Leyland cypress refer to other woods. Their properties should not be substituted for bald cypress data.
What Is Cedar Wood?
Western red cedar is a lightweight softwood native to western North America. It is widely used for siding, fencing, decking, outdoor furniture, and decorative structures.
Despite its name, it is not a true cedar in the botanical genus Cedrus. Other commercially named cedars, including eastern red cedar and northern white cedar, are also different species.
This distinction matters when shopping. The aromatic red wood commonly used in closet lining, for example, is often eastern red cedar rather than western red cedar.

Hardness figures are representative values for dry wood, not guarantees for every board.
Appearance and Grain
Cypress
Cypress offers a relatively light starting color. Its sapwood is commonly pale yellow or nearly white, while the heartwood ranges from light brown to darker or reddish brown.
Clear boards can give furniture and interiors a simple, understated appearance. Knotty grades provide a more rustic look.
Pecky cypress contains distinctive pockets or cavities and is often selected for decorative paneling. Those features should be considered when deciding whether a board suits a smooth tabletop or other functional surface.
Western Red Cedar
Western red cedar commonly displays a mixture of reddish, pinkish, and brown tones. Boards from the same pack may differ noticeably.
That variation is part of its appeal for natural-looking fences and siding. For a more uniform project, sort the boards before installation.
Both species change appearance with exposure. A freshly cut sample will not necessarily match the same wood after several years outdoors.
Which Is More Rot-Resistant?
There is no reliable blanket answer that cypress always outlasts cedar.
The important distinction is heartwood versus sapwood. Natural decay resistance is associated mainly with heartwood, and its level can vary within a species.
Old-growth bald cypress heartwood is particularly well known for durability. The USDA Forest Service’s bald cypress profile explains that second-growth material does not share the same decay-resistant heartwood characteristics.
Western red cedar heartwood also has natural decay resistance. However, a cedar board containing substantial sapwood should not be judged solely by the species’ reputation.
When buying for outdoor use, ask about:
- The exact species.
- Heartwood content.
- Grade and defects.
- Drying condition.
- Suitability for the intended exposure.
Neither wood is immune to decay when water remains trapped around it.
Hardness: Is Cypress Harder Than Cedar?
Bald cypress is harder than western red cedar in standard Janka comparisons: approximately 510 lbf versus 350 lbf.
That makes cypress somewhat more resistant to indentation under comparable conditions. However, both are relatively soft compared with many furniture hardwoods.
Chair legs, dropped tools, and concentrated pressure can dent either wood. A protective finish helps with surface wear and moisture exposure, but it does not substantially increase the wood’s underlying hardness.
Also, “softwood” is a botanical category. It does not mean every softwood is softer than every hardwood.
Weight and Stability
Western red cedar’s low weight makes it convenient for fence boards, siding, and furniture that needs to be moved.
It also has low shrinkage and good dimensional stability. The Western Red Cedar Lumber Association’s properties guide describes these characteristics.
Cypress is generally heavier but remains manageable for many woodworking projects.
Both species still absorb and release moisture. Proper drying, storage, fastening, and allowance for movement matter even when using a relatively stable wood.
Workability: Which Is Easier to Use?
Both cypress and western red cedar are generally easy to cut, drill, and shape with sharp hand or power tools.
Cedar’s softness makes machining easy, but it also means clamps and rough handling can leave marks. Support the wood during cutting to reduce splintering.
Cypress offers a somewhat firmer surface, although knots and uneven grain can still affect the result.
For either species:
- Use sharp blades and bits.
- Predrill near board ends where splitting is a concern.
- Avoid overtightening fasteners.
- Choose corrosion-resistant fasteners suitable for outdoor exposure.
- Test adhesives and finishes on offcuts.
Fastener holding also depends on the joint, board thickness, and hardware. It should not be judged from wood density alone.
Common Uses for Cypress and Cedar
Siding and Exterior Trim
Both are established options for exterior cladding and trim.
Cypress is attractive when a lighter color or painted finish suits the design. Western red cedar offers warm color variation and is available in many siding profiles.
For either material, flashing, drainage, and clearance from wet surfaces are essential.
Fencing
Western red cedar is a familiar choice for fence boards because it is lightweight and widely used for exterior projects.
Cypress can also be suitable where appropriate lumber is available. Treat fence boards and buried posts as different applications: a board that performs well above ground is not automatically suitable for permanent soil contact.
Outdoor Furniture
Both woods can make practical outdoor benches, tables, and chairs.
Cypress provides a slightly harder surface. Cedar offers lower weight, which can be useful for movable seating.
Well-made joints, sound boards, and water-shedding details are more important than simply choosing the wood with the stronger reputation.
Decking
Both species are used for decking, but their relatively soft surfaces can show wear and dents.
Use material sold and specified for decking, with suitable thickness, spacing, and support. Do not assume decorative boards are suitable for structural components.
Interior Projects
Cypress works well for paneling, ceilings, trim, and rustic furniture. Cedar can be used for interior paneling and other decorative work, with the particular species selected for the intended appearance and use.
Which Wood Costs Less?
Neither species is consistently cheaper everywhere.
Cypress may be competitively priced near its growing and milling regions. Cedar may offer better value where suppliers carry it regularly.
Grade can make a larger difference than the species name. Clear, wide boards usually cost more than knotty or narrower material.
Compare equivalent quotes for thickness, grade, moisture condition, surfacing, delivery, and usable yield. A lower price is less useful if the boards require substantial drying, milling, or waste removal.
Do Cypress and Cedar Need Sealing?
An appropriate finish can help manage moisture uptake and preserve the desired appearance. It is not a substitute for natural durability or good construction.
Both woods can be painted or stained with suitable preparation. Select the coating for the application: a siding finish may not suit a horizontal deck.
If you want to retain the original wood color, choose a product offering suitable UV protection. Clear finishes generally provide less protection against color change than pigmented products.
Inspect finished surfaces periodically and maintain them according to the coating manufacturer’s guidance.
Applying a sealer does not automatically make either wood suitable for ground contact.
Cypress vs. Cedar as Firewood
Both can burn as firewood when properly dried. Being softwoods does not limit them to use as kindling.
Their lower density compared with many dense hardwoods means a similarly sized load may require more frequent replenishment.
Use clean, untreated wood with a moisture content of about 20% or less, and follow the appliance manufacturer’s instructions. Never burn painted, preservative-treated, or glued wood products.
A single BTU figure for all “cedar” or “cypress” is misleading because the species, moisture content, and amount of wood in a cord can differ.
Pros and Cons
| Wood | Advantages | Limitations |
|---|---|---|
| Cypress | Light natural color, easy machining, harder than western red cedar, useful indoors and outdoors | Decay resistance varies, relatively soft, availability and price depend on location |
| Western red cedar | Lightweight, stable, attractive color, established exterior uses | Dents easily, variable board color, sapwood offers less decay resistance |
Which Should You Choose?
Choose cypress when you prefer a lighter appearance, want a somewhat harder surface, and can obtain suitable lumber at a reasonable local price.
Choose western red cedar when low weight, warm coloring, and readily available exterior profiles suit your project.
For outdoor work, inspect the boards rather than buying on reputation alone. The right grade, sufficient heartwood, sound construction, and good drainage will do more for long-term performance than the name “cypress” or “cedar” by itself.
