Aspen and alder wood are two popular choices for interior woodworking, each with unique characteristics. These are mainly used for interior furniture. Aspen wood is generally softer and lighter than alder wood. In terms of color comparison, alder wood is darker than aspen.
What is Aspen Wood?
Aspen is a light-colored wood that can range from white to light cream. It is considered a lightweight hardwood with a relatively low density. Aspen wood is commonly used for interior applications such as furniture, cabinets, and millwork.
Aspen is the name of several species with almost similar properties, all native to cold regions. The height of trees of all its species can range from 15 to 30 meters (50-100 feet).
What is Alder Wood?
Alder is a durable and stable hardwood, moderately lightweight with a medium density. Alder wood typically has a light tan to reddish-brown color with a straight and even grain. It is commonly used for furniture, cabinetry, doors, millwork, and molding.
Alder is also the common name for a group of tree species (about 35 or more) native to many areas of the Northern Hemisphere. The height of the Alder tree is about 10- 30 meters. The lifespan of alder trees is approximately 100 to 120 years.

Aspen vs. Alder Wood Workability
Aspen wood is easy to work with hand and machine tools than Alder wood because Aspen wood is softer than Alder; both types of wood hold glue, nail, and screws well.
Alder wood is noticeably softer than other hardwoods and allows easy cutting, shaping, and sanding. Both these woods do not require pre-drilling to insert nails or screws.
If you plan to apply stain, Aspen wood will take stain and paint well. However, staining Alder wood can be challenging because it tends to absorb stains unevenly, resulting in a blotchy finish.

Aspen wood has a fine and uniform grain pattern, contributing to its smooth and consistent appearance. Alder wood has a straight and even grain pattern, much like aspen.
Which is Harder: Aspen or Alder Wood?
Generally, most species of aspen have a lower density than most of the alder species since many species of aspen and alder have different hardness and dry weight. Here are the Janka Hardness values of the most popular wood species of Aspen and Alder. So you can get a idea how hard is that.
Aspen: Quaking Aspen has a Janka hardness of 350 lbf (1,560 N), European Aspen has a hardness of 380 lbf (1,650 N), and Bigtooth Aspen has a hardness of 420 lbf (1,870 N).
Alder: The hardness values for red alder, European alder, and gray alder are 590 lbf (2,620 N), 650 lbf (2,890 N), and 770 lbf (3,410 N), respectively. Alder wood is medium hard, so it is ideal for cabinetry and musical instruments (electric guitar bodies).
