The short answer: you should not directly stack a dryer that is larger than the washing machine on top of it. Manufacturers require that the dimensions and footprint match and that you use a suitable stacking kit. We explain when stacking is possible, why size differences are risky, and what safe alternatives you have to still save space in your laundry area.
The short explanation: when you can and cannot stack
Stacking is possible if your washing machine and dryer are designed for 60 cm width, the feet fit well on a stacking kit, and the dryer is not wider than the washing machine. If your dryer is wider or protrudes at the front, direct stacking is not recommended. The washing machine absorbs vibrations during spinning. If the dryer extends beyond the washing machine’s base, you increase the chance of shifting, damage, and warranty issues. Always use a manufacturer-approved stacking kit or a TÜV-certified solution.
Why placing a larger dryer on a smaller washing machine is risky
With a size difference, the weight of the dryer does not rest stably within the washing machine’s support line. During spinning, dynamic forces can cause an overhanging dryer to slide or tip. This not only increases the risk of damage to both appliances but also leakage or disconnection of connections. Moreover, many manufacturers state that improper stacking without a suitable kit or with size differences voids the warranty.
Noise levels and wear also increase. A dryer that extends beyond the edges of the washing machine amplifies vibrations and can put extra strain on the bearing and suspension. Even small differences in width can cause problems if the dryer's feet do not fit precisely into the stacking kit. Finally, power and condensate connections can be stressed by movement, which is unsafe. Therefore, the rule of thumb is simple: never stack directly if the dryer is larger than the washing machine.
Safe alternatives for size differences
Placing side by side
If your dryer is larger than your washing machine, placing them side by side is the safest and most universal solution. You maintain full stability, minimize vibrations, and have direct access to both appliances at working height with a countertop or washing machine base cabinets for a stable foundation and optimal working height. You can create extra storage space above the appliances with cabinets or shelves.
Stacking in a washing machine cabinet
A sturdy washing machine cabinet can transfer the dryer’s load through the cabinet walls to the floor instead of through the washing machine. Only choose a cabinet designed and tested for this, such as our built-in cabinets for washing machine and dryer. Wasdroom’s washing machine cabinets are TÜV-certified, moisture-resistant finished, equipped with soft-close, and developed to stack washing machine and dryer. If you have a dryer with non-standard dimensions, consult our customer service beforehand or check the installation manual to verify if your combination fits within the allowed dimensions. Also check the Standard built-in dimensions for washing machine cabinets.
Other options
Consider a more compact dryer model or a heat pump dryer with standard 60 cm dimensions, so you can use a stacking kit. If you cannot change the appliance, opt for a tall cabinet setup with appliances on separate levels or a countertop solution with drawers for ergonomics and extra storage, or use washing machine risers to compensate for height or door alignment.
Stacking with equal dimensions - here’s how to do it
If your dryer fits in width and depth, follow this approach:
- Check specifications of both appliances - 60 cm wide, stackable, and maximum weight suitable for the kit.
- Choose a stacking kit compatible with your brands and models. Follow the manual.
- Level the washing machine with a spirit level. Adjust the feet until the machine does not wobble.
- Attach the stacking kit to the washing machine according to the instructions, including locking or straps if provided.
- Lift the dryer onto the kit with two people and lock it in place. Connect power and any condensate drain without kinks.
- Leave at least 1 to 2 cm of space behind and above for ventilation. Read more about the required space behind washing machine/dryer in a cabinet.
Note: the dryer should always be on top. A washing machine should never be placed on a dryer due to weight and forces during spinning.
Checklist and dimensions
| Component | Guideline | Why |
|---|---|---|
| Width | Dryer must not be wider than the washing machine | Prevents overhang and shifting |
| Depth | Small depth tolerance is sometimes okay, no front overhang | Keeps the center of gravity within the base |
| Stacking kit | Always use, suitable for brand and type | Secures and distributes forces safely |
| Weight | Within the load capacity of the kit and cabinet solution | Prevents structural overload |
| Floor | Flat and sturdy, preferably a hard floor | Less vibration and sliding |
| Ventilation | Free space at the back and top, according to the manual | Prevents overheating |
| Connections | Power and condensate drainage without tension or kink | Safety and performance |
Frequently Asked Questions
Can you stack a washing machine and dryer of different sizes?
Not if the dryer is larger. The dryer must not exceed the washing machine in width and must not overhang at the front. Stacking is only responsible with equal dimensions and a suitable stacking kit. With size differences, choose side-by-side or a tested cabinet solution after advice.
Is a stacking kit necessary for a washing machine and dryer?
Yes. Manufacturers require a suitable stacking kit to secure the dryer and distribute forces. Without a kit, the risk of damage increases and the warranty may be voided. Use only kits approved for your models.
Can a dryer be placed on top of a washing machine?
Yes, provided the dimensions fit and you use a stacking kit. The dryer always goes on top, never the other way around. Make sure the washing machine is level and there is sufficient ventilation.
How much larger can a dryer be than a washing machine?
In practice, the dryer must not be wider. A slight depth difference at the back is sometimes allowed, but no overhang at the front. Consult the manual. When in doubt, do not stack.
Does every 60 cm dryer fit on every 60 cm washing machine?
Not always. Pay attention to foot position, compatibility of the stacking kit, depth, and shape of the top panel. Check the product sheets and preferably choose a kit from the same brand or a kit that explicitly supports your models.
What if my dryer is deeper than my washing machine?
A little extra depth at the back is usually not a problem, as long as there is no front overhang and the stacking kit fits. If the dryer is significantly deeper or heavier, side-by-side or a tested washing machine cabinet after advice is the better choice.
Advice from Wasdroom
Wasdroom helps you create a safe and neat setup. Our TÜV-certified washing machine cabinets are made from moisture-resistant board material with a durable melamine coating and feature soft-close. You get a 5-year warranty and 30 days to reconsider. Since there is no specific solution for every dryer that is larger than the washing machine, we advise contacting our customer service first if there is a size difference. We are happy to check whether your combination fits within the allowed dimensions of our Stapel Series and will help you find a suitable side-by-side or cabinet setup.
