When buying or constructing a wood table, understanding its weight capacity is essential for ensuring durability, functionality, and safety. Otherwise, you may end up choosing a table that won’t hold the appropriate load, which could result in breaking or collapsing and injuries.
In this article, our expert woodworkers will help you determine how much weight can a wood table hold safely to prevent such risks.
Wood Tables and Their Maximum Load Capacities
Like any other piece of furniture in your home, your wood tables have a maximum weight limit. This refers to the weight your table is designed to safely support without compromising its structural integrity.
Putting too much load on the table beyond its weight capacity can damage your table, including warping, bending, or collapsing. These structural damages can be irreversible or cost expensive repairs and may significantly reduce the lifespan of your wood table.
Exceeding the weight capacity of your wood table can also pose safety hazards, such as injuring individuals or your pets sitting or standing near it. Additionally, damaging the property it may cause can be costly, especially if you put valuable, fragile items on your table.
Therefore, it is essential to determine the weight capacity of your tables and follow the weight limit when using them in your home.
However, there are many factors you must consider in identifying the weight capacity of your wood table, including the wood type, design, construction, and intended use.
Generally, different types of tables are designed for different purposes and uses, and their weight capacity can vary accordingly. Here are some common types of tables and their average weight capacity.
Table Type | Maximum Weight Limit |
Coffee table | 300 lbs / 136 kg |
Dining table | 330 lbs / 150 kg |
Computer table | 150 lbs / 68 kg |
Workbench | 440 lbs / 200 kg |
Dining bench | 550 lbs / 250 kg |
Folding kitchen table | 440 lbs / 200 kg |
3 Main Factors Affecting the Maximum Weight of Wood Tables
When buying or constructing your wooden table, it is essential to consider the factors affecting its maximum weight or load capacity to ensure its structural integrity, durability, functionality, and safety.
1. Table Material’s Stiffness
The stiffness or rigidity of your table material significantly impacts its weight capacity. Generally, stiffness refers to the ability of the wood to resist deformation or bending when heavy weight is applied.
It relates to how much the tabletop or other structural components can flex or bend when subjected to heavy loads.
This means that if your table wood has higher stiffness, it is expected to hold a higher weight limit since it can better resist deformation and will not tend to bend under a heavier load on the table.
Your table, made of stiffer wood, can support more weight without bowing, sagging, and breaking.
If your table material has lower stiffness, it’s more prone to bending and deformation under heavy loads. It only supports lower weight capacity to prevent structural failure, such as breaking and collapsing.
The stiffness of your table material is an essential factor in determining the maximum load capacity of the table. Below is the list of the general stiffness or the optimal load your table can hold depending on the wood material you use.
Table Wood Material | Stiffness (Mpsi) |
Hickory | 2.16 |
Birch | 2.01 |
Hard Maple | 1.83 |
Douglas Fir | 1.95 |
Red Oak | 1.82 |
White Oak | 1.78 |
Walnut | 1.68 |
Soft Maple | 1.64 |
Cherry | 1.49 |
Mahogany | 1.4 |
Pine | 1.19 |
Cedar | 1.11 |
Redwood | 1.1 |
2. Maximum Bending Strength
The optimal bending strength of a table refers to the maximum amount of bending or deflection it can withstand without experiencing permanent deformation or structural failure.
Generally, it measures the table’s structural integrity and ability to support a perpendicular load applied to the wood grain without collapsing or breaking.
Therefore, the bending strength of your table can affect its weight capacity, as a table with high bending strength will typically have a high weight capacity.
Your table with higher bending strength can better resist bending or deflection caused by heavy loads. This can support higher weight loads while preserving its structural stability.
Generally, the bending capacity of tables depends on the wood material used. So, if you need a table that can hold heavier loads, you must choose a wood that has greater bending strength like the following:
Table Wood Material | Bending Strength (psi) |
Hickory | 20200 |
Birch | 16600 |
Hard Maple | 15800 |
White Oak | 15200 |
Walnut | 14600 |
Red Oak | 14300 |
Soft Maple | 13400 |
Douglas Fir | 12400 |
Cherry | 12300 |
Mahogany | 10700 |
Pine | 8200 |
Cedar | 7500 |
Redwood | 7900 |
3. Maximum Compressive Strength
The compressive strength of your table generally refers to the structure’s integrity, particularly the table legs’ capacity to support heavy weight without collapsing or breaking safely.
The table’s compressive strength varies depending on the design and wood material used. To determine the wood table’s compressive strength, you must measure the weight uniformly applied along its legs through the center.
You must aim for high compressive strength as this equates to greater load capacity that the table legs can support. Here is the compressive strength of different table wooden legs with uniform cross-sectional areas:
Table Wood Material | Compressive Strength (psi) |
Hickory | 9210 |
Birch | 8170 |
Hard Maple | 7830 |
White Oak | 7440 |
Walnut | 7580 |
Red Oak | 6760 |
Soft Maple | 6540 |
Douglas Fir | 7230 |
Cherry | 7110 |
Mahogany | 6460 |
Pine | 4460 |
Cedar | 4560 |
Redwood | 5220 |
Increasing the Maximum Load Capacity of Wood Tables: Here’s How!
If you bought or built a wooden table that turns out to have a lower load capacity than intended, don’t lose hope yet, as there are many ways you can do to increase its weight capacity.
You can use a stronger or thicker wood for the top material to do this. For instance, you can use more durable hardwood instead of softwood or processed wood. If you do not have hardwood, you can add more layers of softwood or plywood for added strength.
You might want to check out the following:
Alternatively, you must distribute the weight evenly across the table surface. Use placemats or tablecloths to help distribute the importance of the load on the table and avoid too much weight on concentrated areas.
Properly using and maintaining your table is also necessary to preserve its structural integrity and load capacity. Avoid putting hot objects directly on the wood surface, as heat and moisture can weaken the wood material and reduce the table’s load-bearing capacity.
Ultimately, it is crucial to follow the capacity limit of your table to avoid damage and prevent accidents that may result from overloading your table.
How to Reinforce Your Table to Bear More Weight
The most effective way to help your wooden table support heavier weight is to reinforce its legs. Essentially, your table’s legs are crucial for keeping the heavy load.
So, you must strengthen them by attaching metal brackets, L-shaped corner braces, or angle brackets to provide extra support and stability, preventing the table from wobbling or sagging.
You should choose heavy-duty brackets, screws, and bolts to assemble your table. These can provide better structural stability and strength compared to standard hardware.
Additionally, you can attach support beams or crossbars between the legs. This will help to distribute the weight more evenly and increase the table’s load-bearing capacity. You can also attach a ribbing vertically along the entire length of the table to evenly distribute the weight.
What Type of Wood Holds the Most Weight?
How Thick Should Your Coffee Table Legs Be?
Ideally, your coffee table’s legs should be 3/4 inches thick and 4 inches wide to support its weight capacity. If you want to strengthen your coffee table’s legs to bear heavier loads, you can make them thicker.
How Should You Make a Table Base?
We suggest you use a T-style for your table base to provide optimum support, especially for a table with a wide surface area. This table base structure is designed to hold a heavier amount of weight without the risk of collapsing.
How Heavy Can Pedestal Tables Hold?
Typically, your pedestal table holds a maximum of 200 lbs or 90.72 kg. However, the weight capacity of your pedestal table varies depending on other factors, such as the kind of wood material used and the size of the table legs.
