In general, a small greenhouse with a 6′ x 8′ or 8′ x 10′ footprint can work for a beginner gardener. However, a larger greenhouse that measures 10′ x 12′ or 10′ x 20′ can accommodate more plants and provide more space for walking around and working. Here are 4 factors to assess when choosing a greenhouse to buy…
1. What Variety of Plants are You Growing?
First and foremost, when considering the type of plants, herbs or edibles that you want to cultivate in your greenhouse, it is essential to determine the size of the structure that can handle the job. Are you planning on growing vegetables, flowers, sprouting seeds or perhaps cultivating small cacti or succulents?
Different plants have varying space requirements. Some may thrive in a compact footprint while others may need a larger area for optimal growth. For instance, if you are looking to grow taller plants or prefer a walk-in greenhouse where you can comfortably move around and tend to your garden, a bigger structure would be ideal.
On the other hand, smaller varieties or seedlings might do well in a narrow nursery with multiple shelves for efficient use of space. Ultimately, understanding what types of plants you intend to grow will help guide you towards choosing the optimal interior dimensions that align with your gardening goals.
Note on Vegetable Gardening: Usually, a small 6′ x 8′ backyard greenhouse can work fine for growing basic vegetables for a family of 2 to 4 people. However, if you want to grow a greater variety of plants, look for a larger structure that measures 10 feet by 12 feet or even 12 feet by 16 feet.
2. How Spacious is Your Backyard?
Second, how much space do you have in your yard? Large open backyards give you more options, since you can install a freestanding pre-fab greenhouse or even 150-foot hoop house kits.
On the other hand, many city dwellers lack garden space and have limited sunlight. As a result, you may do better with a lean-to greenhouse that hugs the side of your house or a fence. They require minimal ground area but can provide a great protected growing environment in a sunny location.
Note: Many backyard gardeners admit that they grow out of their greenhouses pretty quickly. They advise others to “size up” when shopping for a plant nursery because you’re likely to need more space than you initially think.
Also, consider area that you’ll need for things like heaters, lights, soil, a gardening bench and simply walking around.
3. Do You Want a Portable Greenhouse?
Some structures are more permanent than others. For example, some house frames need a sturdy foundation and not meant to me moved around. If you live in an area that gets lots of wind or some snow, a sturdier metal-frame greenhouse may be the better option.
Conversely, pop-up greenhouses set up in minutes and can fold down just as quickly for seasonal storage. They typically cost less, but don’t last as long and aren’t as sturdy.
That said, these temporary style can be ideal for people who move around or who only need a seasonal nursery for their plants.
4. What’s Your Greenhouse Budget?
Third, decide on a budget. Basic backyard greenhouse kits range from $100 to over $1,000 and more. Kits typically include sides, roof, doors and venting, but they don’t usually include shelves or other accessories.
When it comes to greenhouse options, pop-up soft shell tents are typically the most budget-friendly choice, followed by tunnel style, polycarbonate panel, wooden, and aluminum frame structures. Keep in mind that larger sizes may come with a higher price tag upfront but often offer a lower cost per cubic foot in the long run. Consider your specific needs and space requirements before deciding on the best greenhouse for you.
What I like about kits is that you can assemble them yourself, which gives you the opportunity to save some money. In addition, they come with easy-to-follow instructions on how to put them together. Therefore, there’s not a lot of guesswork, and “construction” goes fairly quick.

In Conclusion:

Optimal greenhouse dimensions should balance your current needs with room for growth, as many gardeners find they require greater capacity over time. Initially considering these factors allows you to discover a greenhouse that maximizes your gardening activities, allowing for flexibility and efficiency in plant cultivation.
