The short answer: a dryer that's larger than the washing machine shouldn't be stacked directly on top of the washing machine. Manufacturers require that the dimensions and footprint match, and that you use a suitable stacking kit. We'll explain when stacking is acceptable, why a size discrepancy is risky, and what safe alternatives you can use to save space in your laundry room.
The short explanation: when are you allowed to stack and when are you not allowed to stack
Stacking is possible if your washer and dryer are designed for a width of 60 cm, the feet fit securely on a stacking kit, and the dryer is no wider than the washer. If your dryer is wider or protrudes from the front, direct stacking is not recommended. The washing machine absorbs vibrations during the spin cycle. If the dryer protrudes beyond the base of the washer, you increase the risk of shifting, damage, and warranty issues. Always use a manufacturer-approved stacking kit or a TÜV-certified solution.
Why a larger dryer on a smaller washing machine is risky
If the size is different, the dryer's weight won't rest stably within the load line of the washing machine. During the spin cycle, dynamic forces are created that can cause an overhanging dryer to slide or tip over. This not only increases the risk of damage to both appliances, but also of leaks or loose connections. Furthermore, many manufacturers state that improper stacking without the appropriate sealant or in the event of a size difference will void the warranty.
Noise levels and wear also increase. A dryer that extends beyond the edges of the washing machine amplifies vibrations and can place additional strain on the bearings and suspension. Even small differences in width can cause problems if the dryer's feet don't fit neatly into the stacking kit. Finally, the power and condensation drain connections can become live during 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
Place 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 complete stability, minimize vibration, and have direct access to both appliances at working height with a countertop or washing machine base units for a stable base and optimal working height. You can create additional storage space above the appliances with cabinets or shelves.
Stack in a washing machine cupboard
A sturdy washing machine cabinet can transfer the load of the dryer through the cabinet walls to the floor instead of through the washing machine. Only choose a cabinet designed and tested for this purpose, such as our built-in cabinets for washing machines and dryers . Wasdroom washing machine cabinets are TÜV-certified, moisture-resistant, and equipped with soft-close technology. They are designed to fit a washing machine and dryer on top of each other. If you have a dryer of a different size, please consult our customer service beforehand or consult the installation manual to check whether your combination falls within the permitted dimensions. Also, check the standard installation dimensions for washing machine cabinets .
Other options
Consider a more compact dryer model or a heat pump dryer with a standard 60 cm footprint, so you can still use a stacking kit. If you can't switch appliances, choose a tall cabinet layout with appliances on separate levels or a countertop solution with drawers for ergonomics and extra storage space. Or use washer risers to compensate for height or door misalignment.
Stacking with equal dimensions - this is how you do it
If your dryer does fit in terms of width and depth, follow this approach:
- Check specifications of both units - 60cm wide, stackable and maximum weight that fits on the kit.
- Choose a stacking kit that's compatible with your brand and model. Follow the instructions.
- Level the washing machine with a spirit level. Adjust the feet until the machine doesn't wobble.
- Attach the stacking kit to the washing machine according to the instructions, including any locking or tension straps if included.
- With two people, lift the dryer onto the kit and secure it. Connect the power and, if necessary, the condensation drain without kinks.
- Allow at least 1 to 2 cm of space behind and above for ventilation. Read more about the required space behind a washer/dryer in a closet .
Note: The dryer should always be placed on top. A washing machine should never be placed on top of a dryer due to the weight and forces exerted during the spin cycle.
Checklist and dimensions
| Element | Directive | Why |
|---|---|---|
| Width | The dryer must not be wider than the washing machine | Prevents overhang and shifting |
| Depth | Small depth tolerance is sometimes ok, no front overhang | Maintains center of gravity within the base |
| Stacking kit | Always use, suitable for brand and type | Fixes and distributes forces safely |
| Weight | Within the load capacity of the kit and cabinet solution | Prevents structural overload |
| Floor | Flat and sturdy, preferably hard floor | Less vibration and sliding |
| Ventilation | Free space behind and above, according to manual | Prevents overheating |
| Connections | Current and condensate drainage without tension or kink | Safety and performance |
Frequently Asked Questions
Can you stack a washer and dryer of different sizes on top of each other?
Not if the dryer is larger. The dryer must not exceed the width of the washing machine and must not overhang the front. Stacking is only justified if the dimensions are the same and a suitable stacking kit is used. If the dimensions differ, choose side-by-side or a tested cabinet solution after consulting with us.
Is a stacking kit needed for a washer and dryer?
Yes. Manufacturers require a suitable stacking kit to secure the dryer and distribute the load. Without a kit, you increase the risk of damage and may void your warranty. Only use kits approved for your specific model.
Can a dryer be placed on top of a washing machine?
Yes, provided the dimensions are correct and you use a stacking kit. The dryer should always be on top, never the other way around. Make sure the washing machine is level and there's adequate ventilation.
How much bigger can a dryer be than a washing machine?
In practice, the dryer should not be any larger in width. A slight depth difference at the back is sometimes acceptable, but no overhang at the front. Consult the manual. If in doubt, do not stack.
Does every 60cm dryer fit on every 60cm washing machine?
Not always. Pay attention to foot position, stacking kit compatibility, and the depth and shape of the top. Check the product sheets and preferably choose a kit from the same brand or one that specifically supports your models.
What if my dryer is deeper than my washing machine?
A little extra depth at the back is often not a problem, as long as there's no front overhang and the kit fits. If the dryer is significantly deeper or heavier, a side-by-side or a tested washing machine cabinet, as recommended, is the better option.
Advice from Wasdroom
Wasdroom helps you create a safe and tidy setup. Our TÜV-certified washing machine cabinets are made of moisture-resistant board with a durable melamine coating and feature soft-close technology. You get a 5-year warranty and a 30-day return policy. Because there's no specific solution for every dryer larger than the washing machine, we recommend contacting our customer service first if you have a size discrepancy. We're happy to check whether your combination falls within the permitted dimensions of our Stacking Series and help you find a suitable side-by-side or cabinet configuration.
