Wobble Wedge Hard Shims: Best Overall Choice

Wobble Wedge hard shims provide the most reliable structural support for heavy-duty outdoor tables. Their rigid plastic composition prevents the compression often found in softer materials, ensuring the table height remains consistent over time. They are ideal for use on concrete or stone patios where high-load capacity is essential.

The distinct interlocking ridge design allows these shims to be stacked securely without slipping. This makes them a top-tier choice for tables that require significant height adjustments on drastically sloped surfaces. Their durability under extreme temperature fluctuations makes them a permanent, set-and-forget solution.

For those managing heavier professional-grade tables or permanent outdoor installations, these are the gold standard. They bridge the gap between temporary fixes and professional masonry work. If durability and structural integrity are the primary concerns, these shims are the obvious investment.

Shepherd Hardware Rubber Wedges: Best Grip

When table legs rest on slick surfaces like sealed pavers or polished concrete, sliding becomes a significant issue. Shepherd Hardware rubber wedges solve this by utilizing high-friction material that effectively locks the leg into place. The soft, pliable nature of the rubber allows it to conform slightly to the table foot, increasing surface area contact.

This grip is particularly advantageous in areas prone to high wind, where a table might otherwise shift or rattle. Because they are soft, they also act as a dampener, reducing the noise created by intense gameplay. They are exceptionally easy to position and adjust during the initial setup process.

These wedges are the perfect match for households that prioritize stability and noise reduction over extreme height adjustments. While they may compress slightly more than hard plastic, their anti-slip performance is unmatched. If the priority is keeping the table anchored firmly on smooth, hard ground, look no further.

Broadfix Assorted Shims: Best Value Option

Broadfix shims are the utility player of the leveling world, offering a variety of thicknesses in a single package. This versatility is vital when dealing with surfaces that have inconsistent slopes, such as natural stone patios. Having multiple sizes on hand allows for precise micro-adjustments that prevent the “see-saw” effect.

The material is sturdy enough to hold significant weight while remaining easy to snap or trim to size. This customization is incredibly useful for hiding the shim beneath the foot of the table for a cleaner aesthetic. It removes the guesswork involved in buying the perfect size before assessing the terrain.

For those who want to level multiple pieces of outdoor furniture or prefer to keep a supply in the garage, these kits are the most cost-effective approach. They are the ideal choice for someone who values preparedness and versatility. If the goal is to have a solution for every potential leveling scenario, this is the best value available.

EZ Shim Heavy Duty: Best for Outdoor Pool

Outdoor pool tables require a higher standard of precision than almost any other game table. EZ Shim heavy-duty shims are engineered to handle the substantial weight of slate-bed tables without failing or shifting. Their broad footprint distributes pressure evenly, preventing the table legs from sinking into or damaging underlying patio materials.

The material is highly resistant to moisture, making it an excellent choice for tables kept near pools or in humid environments. Unlike wood or basic plastic, these will not rot, warp, or crack when exposed to frequent water splashes. They maintain their thickness under the sustained, crushing weight of heavy game hardware.

If the setup involves a high-end pool or air hockey table, do not compromise on the shim quality. These provide the consistent, rock-solid base necessary for the accuracy required in cue-sport games. For those with heavy equipment that demands long-term stability, these shims are the clear, reliable path forward.

Pinheads Adjustable Levelers: Best Upgrade

Pinheads adjustable levelers represent a departure from standard shims by offering a threaded, screw-in mechanism. This allows for precise, millimetric adjustments simply by rotating the leveler, eliminating the need to stack multiple loose wedges. They are the most professional solution for leveling tables with adjustable feet.

Installing these provides a refined look, as they blend seamlessly into the existing leg structure of the table. They are superior in environments where frequent, minor leveling adjustments are needed due to ground shifts from seasonal temperature changes. Once installed, they provide a much cleaner, more integrated appearance than traditional loose shims.

Choosing these levelers is a commitment to a premium, long-term setup. They are ideal for users who dislike the maintenance of checking and replacing loose shims periodically. If the objective is a high-performance, polished, and permanent leveling solution, these are the superior choice.

Outwater Flexible Shims: Best for Soft Grass

When a game table is positioned on a lawn, the soil density often changes, leading to sinking legs. Outwater flexible shims offer a wide surface area that prevents legs from boring into the ground, effectively distributing the weight across the soft surface. Their slight flexibility allows them to “float” with the ground rather than fighting against the natural give of the soil.

These shims are especially useful in transitional seasons when the ground may alternate between soft and hard. They prevent the common issue of one leg digging in while others remain perched on the grass. By creating a wider base, they provide the necessary friction and support to keep the table frame from twisting.

For casual backyard setups where the table resides on lawn rather than a patio, these shims are the most practical solution. They are simple to install and provide the necessary support to keep gameplay balanced on uneven turf. For those seeking stability on organic, shifting ground, these are the recommended hardware.

Choosing the Right Shims for Uneven Patios

Leveling a table on a patio starts with identifying the most extreme slope points. Use a carpenter’s level to determine which corners require the most lift before sliding any shims into place. It is often better to use one thick shim rather than stacking three thin ones, as stacked shims can become unstable over time.

Always consider the weight of the table against the material of the shim. Lightweight plastic may work for a folding ping-pong table, but a heavy slate pool table requires rigid, high-density materials that won’t deform. Assess the surface texture of the patio as well; smooth tiles may require rubberized shims for grip, whereas rough concrete allows for a wider range of rigid options.

Avoid using makeshift items like folded paper or scraps of wood, as these materials break down rapidly when exposed to humidity and rain. These DIY fixes often lead to a table becoming unbalanced again within a few weeks. Invest in purpose-built leveling equipment to ensure that the time spent leveling isn’t wasted by repeating the process constantly.

Assessing Your Game Table Weight and Footprint

The weight of the table dictates the mechanical requirements for the shim. A lightweight, mobile game table exerts low pressure, meaning small plastic wedges are usually sufficient. However, a permanent, heavy-duty table requires a wide footprint to ensure the pressure is spread out, preventing the legs from damaging the patio surface.

Measure the footprint of each table leg to ensure the chosen shims provide full contact. A shim that is smaller than the table foot creates a focal point of stress, which can lead to cracks in both the shim and the patio surface. If the table feet have a non-standard shape, such as a ball-and-claw design, consider using a wider shim plate to bridge the gap effectively.

Consider the intended frequency of movement for the table. Tables that are frequently folded and stored require shims that can be easily recovered and repositioned. Tables that stay in a fixed, permanent location benefit from shims that can be anchored or glued into place. Match the equipment to the intended use case to ensure the most efficient setup possible.

Step-by-Step Leveling Guide for Perfect Play

Start by placing the table in its final position and using a long spirit level to check the lateral, longitudinal, and diagonal planes. Identify the lowest leg and place the appropriate shim beneath it, taking care to keep the table steady during the process. Having a second person assist by slightly lifting the table corner makes this step significantly safer and more precise.

Once the initial adjustment is made, check the level again from all angles, as lifting one corner can shift the weight and change the pitch of the entire surface. If the table remains unstable, adjust the adjacent legs until all four corners have firm contact with the ground. A stable table should not rock when moderate, intentional pressure is applied to opposite corners.

After leveling is complete, perform a “roll test” on the table surface if applicable, using a ball to see if it drifts in any direction. Small drifts indicate that the table is still slightly off-center and may require a slight turn or addition of a thinner shim. Patience during this phase prevents frustration during actual gameplay sessions.

Weatherproofing Tips to Prevent Sinking Legs

Outdoor game tables face the constant challenge of environmental wear, particularly at the connection point between the leg and the ground. Moisture is the primary enemy, as it softens wood or promotes the decay of surrounding soil. Placing a weather-resistant mat or a specialized foot pad beneath the shim can provide a vital barrier against ground moisture.

Regularly check the area around each table leg for signs of erosion or sinking, especially after heavy rain. If the ground has become saturated, the table may need to be re-leveled once the area has dried, as the soil will contract unevenly. Keeping the area surrounding the legs clear of leaves and debris prevents moisture accumulation that can damage the shim and the leg base.

Finally, consider applying a coat of marine-grade sealant or a rubberized coating to the bottom of the table legs if they are made of metal or wood. This reduces the need for constant maintenance and helps the leveling shims last significantly longer. Protecting the base of the table is just as important as selecting the right leveling gear for long-term outdoor use.

With a properly leveled surface, the focus remains entirely on the game rather than the equipment. Take the time to dial in the base now, and every subsequent match will be defined by pure, uninterrupted play. Get outside, set the table, and enjoy the game.
