What is a vegetable garden yield calculator?

The plant yield refers to the amount of produce you get, depending on the number of plants, which in turn depends on the spacing required between plants and the area of the plantation that you have available.

This vegetable planting calculator helps you decide how much produce you can possibly get, based on your crop of choice and the number of rows of vegetation you're going for.

With the world moving slowly towards sustainable sources of energy and food, it's only a matter of time before your amazing gardening skills put you in the spotlight! This harvest yield calculator should help push you in the right direction toward growing your own veggies 🥕
and possibly making a salad 🥗 from your own garden!

How do I use this vegetable yield calculator to calculate garden size?

Kudos on starting your own vegetable garden 👏! Now that you've decided to go green 💚, here's how you can use this garden calculator to get the best out of your plants 🌿!

Enter the following details in this vegetable planting calculator to calculate your harvest yield:

  1. In order to estimate the crop yield, the first step is surprise, surprise, to choose a crop! Well, duh 😏!
  2. Next, you may want to measure the space you have and enter the length of a row of saplings.
  3. You'd also need to enter the number of rows of such saplings you want.
  4. Ta-da! The vegetable yield calculator will not only show you the estimated yield that you'll get but also calculates the garden/farm area that you'll need! (The area considers a 1.5-foot gap between rows and along the boundaries for you to comfortably tend to the plants.).

Time to become the planner of a small farm, do a soil test, and stock up on some mulch and fertilizer for your plants!

You may find our fertilizer calculator helpful in determining how much fertilizer you'll need – some may even prefer a water-soluble fertilizer for better nutrient absorption of the plants!

How do I choose a crop in the crop calculator?

Selecting a crop in the vegetable yield calculator is an important choice. The type of crop 🌾 that you want to grow would depend a lot on your consumption pattern, the average temperature in your region, and also a little on plants' yield rate.

Some of the most popular plants with high yields are:

  • Tomatoes 🍅;
  • Peppers 🌶️;
  • Corn 🌽 (Try out our specialized corn yield calculator if you're one of those corn-lovers!);
  • Beans;
  • Peas;
  • Cucumbers 🥒; and
  • …many more!

You may choose any of these among many other crops in the vegetable yield calculator to check how your yields would vary.

In addition to the climate and nature of the crop, the crop yield primarily depends on the soil too. If you're going to be planting the crops in a pot instead of directly on the ground, potting soil will give a better plant yield compared to natural soil.

Other things to keep in mind

While using the garden yield calculator to plan out your own farm/garden and measure plant yield, you may also want to consider the amount of water required by the plants and the watering frequency.

Some people prefer a nice lawn surrounding their veggie garden, and if you're one such person, here are a few additional tips 💡:

  • You could grow grass from grass seed, and we have a grass seed calculator that can help you estimate how many seeds you'll need for a particular area.
  • You may place a ready-made sod instead of growing grass from scratch.
  • If you're growing grass, you may need a handy lawn mower to trim the grass from time to time.
  • What's more, if your lawn is HUGE (spread across several acres), you could also let some cattle 🐄 graze on it!

Well… that's that! Have a leafy 🍃 experience!


What is an average home garden size?

  • Individual – 100 sq. ft.;
  • Couple – 200 sq. ft.;
  • Average family (3-4 members) – 300-500 sq. ft.;
  • A large family (5+ members) – 600-800 sq. ft.; and
  • Very large family (8+ members) – 1000+ sq. ft.

How many broccoli plants per person should we plant?

In order to determine how many broccoli plants you will need in your vegetable garden, we could follow a typical pattern of 2-4 plants per person. So for a family of 4, you may consider planting around 15 saplings.

What is the ideal vegetable garden size?

While there's no ideal size for a vegetable garden, a good size for a beginner to start working on a vegetable garden would be 6×6 feet. You could experiment with your crop yields and progressively become a planner of a small farm.

What size should a raised vegetable bed be?

As a guide for planting vegetables on a raised bed, the most popular choice is to have the bed elevated by 11 inches. You'll be able to achieve sufficient drainage for most crops at this height.
