If you are interested in planting vegetables but find yourself asking how do I calculate the spacing distance needed to plant vegetable seeds, you have come to the right place. This vegetable seed calculator will help you compute the space required to plant your seeds and the necessary spacing distance for transplanting the seedlings when the time is right.
With this vegetable seed calculator, we covered detailed information on:
 How to use our vegetable seed calculator;

How to use our vegetable seed calculator
This vegetable seed calculator is two calculators in one. The first part allows you to calculate the required distance when planting different vegetable seeds. The second section will give you the appropriate spacing for transplanting seedlings ๐ฑ.
In each section, you need to identify the type of vegetable ๐ you are dealing with. Next, you need to state the length of the row you are cultivating, followed by the number of rows.
Once you have entered these values, our calculator will give you the required distance for planting and the number of seedlings or seeds that can fit in the given space. ๐
What is the formula used to calculate the vegetable seed spacing?
To calculate the number of seeds for growing vegetables in a set space, we use the formulas:
We then round the result down to the nearest integer. Next we apply the following:
We round down the number of seeds per row to ensure that if the number of seeds per row is a decimal value (e.g., 5.6), the decimal place is truncated before we multiply by the number of rows. We use this method because if we do not round down and there are leftover spaces in each row when we use the decimal value in our calculation, it will add all the extras together. That would give the false impression that we can add the extra of each row together to create extra planting space. To avoid this, we must round down.
In this way, if a row is 100 inches in length and the planting distance is 12 inches, the extra 4 inches will not be added to the extra distance for the next row to create an incorrect number of seeds due to the difference left over from each row.
How to grow vegetables from seeds? What is the required planting distance?
Most vegetables can be grown from seeds. However, this is not always the preferred method for gardeners because growing plants from seed can be timeconsuming and require some knowhow.
An avid gardener on a budget knows to harvest seeds from this year's crops for next year's planting season. This helps to save money and makes him more selfsufficient. As such, learning to grow plants from seeds is an essential step for gardeners, particularly those looking to grow organic crops.
Growing vegetables from seed require knowledge of the distance for planting different seeds. This measurement is not the same when transplanting seedlings, however. In the table below, we have outlined the spacing distance, in inches, for planting different vegetable seeds and seedlings. These measurements are also the ones we used in our vegetable seed calculator.

How to prepare a row for growing vegetables?
Preparation for planting vegetable seeds differ from plant to plant. These differences range from temperatures, PH balance, and water retention. It is essential to know the requirements for different seed types before planting.

Artichoke:
Thrives best in deep, welldrained sandy or loamy soil They should be kept well watered.
Start artichoke seeds indoors 1/4 inch deep. You may transplant them after 60 days. Artichokes are best for warm climates. 
Beans:
Green beans can grow in almost any soil type. However, they grow best in warm climates where the soil is welldrained, and they have access to plenty of sunlight. Plant seeds 1 inch deep when there is no danger of frost. They do not require much water, so soil types with good water retention are best avoided.
To avoid clumping together, you should adequately till the soil to prepare for growing beans. You may till the soil thoroughly several times before planting. 
Beets:
Beets grow best in cold temperatures, in deep soil that is welldrained and loose. Plant seeds about 1/2 inch deep. 
Cole Crops:
Broccoli, cabbage, cauliflower, collards, kale, kohlrabi, lettuce, mustard, turnip, watercress, spinach, and Brussels sprouts are all examples of cole crops. They grow best in cool temperatures in sandy loom soil. As such, when growing these crops in warmer climates, it is best to grow them in a shade house away from direct sunlight. 
Carrots ๐ฅ :
Carrots grow best in loose, sandy, welldrained soil. Plant carrots 1/2 inch deep in cool temperatures. 
Celery :
Celery is bestgrown in soil that retains moisture well. This is because it requires lots of water. There is no need to cover celery seeds. Simply soak them for 24 hours, sprinkle them on the earth and leave them to germinate. 
Corn ๐ฝ:
Corn is best grown in welldrained sandy soil. It is best to plant corn in an area with plenty of sunlight.
Plant corn about 1 inch deep. 
Onions ๐ง :
Onions need sunlight and welldrained soil to grow well. When planting onions from seeds, you should plant them 1/4 inch deep. 
Melon:
When growing melons, it is best to do so in deep sandy or sandy, welldrained loom soil. Melons are warmweather crops, so they should not be planted when there is a danger of frost.
Melons should be planted 1 inch deep. 
Okra:
Okra is best grown in full sunlight, in welldrained soil, 1 inch deep. 
Peppers๐ถ :
Peppers grow best in welldrained soil where there is plenty of sunlight. 
Potatoes ๐ฅ:
Potatoes grow best in loose, welldrained soil where there is plenty of sunlight. 
Radishes:
This type of vegetable should be planted 1/2 inch deep in loose, welldrained soil. This vegetable should be grown in cool temperatures. 
Squash:
Squash is a crop best grown in warm temperatures. It is cultivated in sandy soil and should be planted 1 inch deep.
How many brussel sprouts seeds can I plant in a row?
We plant Brussel sprout seeds 12 inches apart. So on a row 100 inches long, we will calculate the number of seeds we can grow using this formula: 100/12 = 8
.
That gives us 8 Brussel sprout seeds.
Are there any vegetables with seeds?
Yes. The list of vegetables with seeds is extensive. There are peppers, cabbage, watermelon, okra, peas, beans, squash, tomatoes, eggplants, cucumbers, carrots, garlic, pumpkin, etc.
How do I decide how many pepper seedlings to transplant to a row?
To decide the number of pepper plants or seedlings to transplant to an area 1000 inches long we:
 Get the distance of pepper seedlings from the table (
12 inches
).  Divide the length of the row by the given distance between seedlings (
1000/12 = 83.33
).  If this is not a whole number, round down the result (
83
).
This answer is the total number of pepper plants you should have in the area.
What does a gardner need to know when transplanting vegetable seedlings?
Here are three tips you need to know when transplanting vegetable seedlings:

The ideal weather for transplanting vegetables is when it is drizzling.

It is best to prepare the land ahead of transplanting. In this way, we will make the process as easy and 'painless' as possible for the plants.

Keep the soil about the roots from the original container. Also, handle seedlings with care to avoid undue damage to the roots.
