If you are looking for the best affordable planters, the direct answer is that the listing data we collected has no prices, so no planter in this guide can be named the cheapest. What the data does have is size, stated capacity, material and drainage for ten planter listings. Those are the figures that decide value once you look up the price on the product page. A planter that costs less per gallon of soil is the better buy, even when its sticker price is higher. This guide shows how to compare value on those terms and works through the listings with that method.

Quick answer

• You cannot rank these planters by price from the listing data. The listings carry no price, so the cheapest option is one you check on the product page yourself.
• Rank by value, not by size. Divide the price you see by the stated gallons. The planter with the lowest figure gives you the most soil for the money.
• Use the stated capacity with care. The Elevon bed’s 18 cubic feet equals its outer box, and the FOLLOOK figure is larger than its outer box. Neither can be taken as soil volume without checking.
• For a small indoor plant, look at the two small pots. The RooTrimmer and Xiaan Jiaju pots are the only pots in this set under a foot across.

Why the price is the last number to check

A price tells you what you pay. It does not tell you how much soil you get. Two planters at the same price can differ several times over in the volume they hold, and the difference shows up only in the stated capacity and size. That is why this guide sorts the listings by what they state about volume, drainage and footprint before it says anything about cost.

The listings state capacity in different units. Some give gallons, some give liters, some give cubic feet and one gives cubic inches. To compare them you need one unit. One cubic foot holds 7.48 US gallons, one US gallon is 3.785 liters, and one US gallon is 231 cubic inches. Once every figure is in gallons, the cost per gallon is the price divided by the stated gallons. That number, not the sticker price, is what makes a planter affordable in the sense that matters for soil.

The method has one limit. The cost per gallon is only as good as the capacity figure. A stated figure that is larger than the outer box cannot be a soil volume, and a figure that equals the outer box leaves no room for the walls. So the next step is to check the figures against the size.

Reading the capacity figures

Outer volume is simple arithmetic. Length times width times height gives cubic inches, and dividing by 1,728 gives cubic feet. Soil volume is always smaller than the outer volume, because walls, the base and any tray take up space. A figure at or above the outer volume needs a second look.

Listing	Size in the listing	Capacity in the listing	Outer volume, worked out	What it tells you
Elevon 2-pack galvanized raised bed	72 x 36 x 12 in	18 cubic feet	72 x 36 x 12 = 31,104 cubic inches, or 18 cubic feet	The stated figure equals the outer box, so the walls take no room in the listing’s figure
FOLLOOK 53.1-inch planter with trellis	15.7 x 31.5 x 53.1 in	442 liters	15.7 x 31.5 x 53.1 = 26,260.6 cubic inches, or 430.3 liters	The stated figure is larger than the outer box, so it cannot be a soil volume
Ciao Stilista wheeled bed	14.2 x 15.7 x 47.2 in	10,120.64 cubic inches	14.2 x 15.7 x 47.2 = 10,522.8 cubic inches	The stated figure is about 96 percent of the outer box, a plausible share once walls are allowed for
Generic 3-tier wicker planter	5.9 x 15.7 x 14.5 in	19 gallons	5.9 x 15.7 x 14.5 = 1,343.1 cubic inches, or 5.8 gallons	The stated 19 gallons is far above the outer box, and the listing does not explain the gap
VEVOR round galvanized bed	23.64 x 23.64 x 11.4 in	3.14 cubic feet	A round bed of that outer size holds about 2.9 cubic feet	The stated figure is higher than the listed dimensions give

The Ciao bed is the one case where the stated figure and the outer size agree in a way that a buyer can rely on. Its 10,120.64 cubic inches is about 96 percent of the outer box, which leaves room for the walls. The Elevon figure is the opposite case. Its 18 cubic feet equals the outer box exactly, so the figure reads as the box itself rather than the soil it holds.

The FOLLOOK listing gives 442 liters. Its outer box works out to about 430 liters, which means the stated figure is about 12 liters larger than the box that holds it. The listing does not say what the figure measures, so do not use it for soil.

The VEVOR bed’s figure of 3.14 cubic feet matches a round bed that is two feet across and one foot deep, which is the size its title suggests. The listed outer dimensions, though, give about 2.9 cubic feet for a round box of 23.64 inches across and 11.4 inches high. The difference is small, but the stated figure is larger than the listed dimensions support.

Turning capacity into value

Here is the method with the figures from the table, using no prices. Suppose two planters sell for the same price on their product pages. The Ciao bed states 5.86 cubic feet, and the Elevon listing states 18 cubic feet. On the stated figures the Elevon bed holds about three times the volume. The Elevon figure equals its outer box, though, so the true soil volume will be lower, and the gap between the two beds is probably smaller than the stated figures suggest.

For the same reason, do not compare the Generic wicker planter’s 19 gallons with another planter’s figure without checking. Its outer box works out to about 5.8 gallons, so its stated capacity is either the total of several parts or a figure that the listing does not support. Treat the outer size as the ceiling for any comparison, and use the stated figure only where it sits below that ceiling.

The practical rule is this: divide the price by the lower of the two figures, the stated capacity or a sensible share of the outer volume. That gives you a cost per gallon you can defend. It is a rule of thumb, and it does not replace a look at the product page, but it stops the largest number on a listing from winning by default.

What the drainage claims need

Drainage is the most important check that a price cannot answer. The University of Maryland container page says that every container needs adequate holes or slits so that excess water drains, which keeps roots from drowning and rotting. Several planters in this set state a drainage hole, and the FOLLOOK planter includes a drain plug. A planter without a hole in the base is the one that most often needs a second look, and the same Maryland page says a bottom layer of rocks, gravel or broken pot shards does not improve drainage.

The Illinois Extension container drainage page calls the gravel idea a myth. It also warns about pots with permanently attached saucers, because emptying the overflow can be difficult or impossible. That warning matters for any planter with a tray. The TDDSS bed, for example, includes a tray, and its listing does not say whether the tray lifts out. A tray that stays full holds water against the roots, so check that the tray comes out before you buy.

The Iowa State container page says that when you water a container you should keep watering until water flows from the drainage holes, and that containers need much more frequent watering than garden beds. The Iowa State potting media article says that when soil is placed in a container, a lack of depth can deter drainage, and that plants needing excellent drainage can be easier to care for in taller pots than in shorter ones. Those two points are the reason depth matters as much as capacity.

Matching the planter to the plant

Almost every listing in this set gives an overall height, and almost none gives the depth of the soil inside it. Use the height as a rough guide to how much room the roots have, and treat it as an estimate. Among the beds, the TDDSS bed has the greatest stated height at 17.3 inches, followed by the Generic tier at 14.5 inches and the Elevon bed at 12 inches. The RooTrimmer pot is 6.4 inches tall, the Xiaan Jiaju pot is 5.72 inches tall, and each CADUKE container is 5.5 inches tall. Those small heights suit herbs and small plants better than root vegetables.

The Iowa State potting media article supports taller pots for plants that need excellent drainage. A planter 5.72 or 6.4 inches tall is shallow by that standard, so reserve those pots for plants that do well in a small space. The FOLLOOK planter is the tallest listing at 53.1 inches, but the listing does not say how that height divides between the trellis and the planter, so it does not show how deep the soil is. Check the stated soil depth on the product page before you choose any planter for a deep-rooted plant.

Planning the footprint: a worked example

Suppose a wall of your patio is 96 inches long, and you want a row of beds along it. The TDDSS bed’s width is 16 inches. Five of them take 5 x 16 = 80 inches, which leaves 96 – 80 = 16 inches for a walkway or a chair. That row fits, but it leaves no room for a gap between the beds, so check the spacing you want before you buy.

The Ciao bed is 15.7 inches wide and 47.2 inches tall, so two beds placed side by side take 2 x 15.7 = 31.4 inches of width. The same method works for any planter: multiply the width by the number you want, add the gaps, and compare the total with the floor you have. Do not add the depth to the width, because depth is the side you reach across, not the length you walk along.

Choosing by use

Small indoor plants need a small pot, and the two small pots in this set are the RooTrimmer 10-inch pot and the Xiaan Jiaju ceramic pot. The RooTrimmer pot states a capacity of 2.62 gallons and drainage holes, and it can go indoors or out. The Xiaan Jiaju pot is listed for indoor use only and gives no capacity, so use it for a small plant and a dish underneath.

A balcony needs a planter that fits the rail or the corner. The EINYEXW railing boxes are 30 inches long and 5.5 inches high, and they come with coco liners and adjustable brackets. The brackets are listed to fit rails from 2 to 6.3 inches wide, so measure the rail before you buy. For a planter you want to move, the Ciao bed has 360-degree wheels that lock, and the FOLLOOK planter has lockable wheels and a drain plug.

A patio or yard needs a bed with a clear footprint. The Elevon pair is a galvanized open-bottom bed in a 72 by 36 inch footprint, and the VEVOR round bed suits a yard where a round shape fits. The CADUKE set puts four containers in one frame, each 7 by 16.9 by 5.5 inches, so it works for several small herbs. The Generic wicker tier adds a detachable bottom shelf, which the listing describes as a place for tools or pots.

Mistakes to avoid

• Choosing by the largest stated number. The FOLLOOK figure is larger than its outer box, and the Generic figure is far above its outer box. The biggest number on a listing is the one to check first.
• Comparing prices without a common unit. Gallons, liters and cubic feet do not compare until you convert them.
• Treating a planter as a bed without a stated depth. Many listings give only an overall height, which does not tell you how deep the soil is.
• Skipping the drainage check because the planter is cheap. A planter with no hole in the base and no removable tray will hold water against the roots, whatever it costs.
• Adding gravel for drainage. The Illinois and Maryland container pages both say gravel does not improve drainage.

Five checks before you buy

1. Look up the price on the product page, then divide it by the stated gallons after converting the capacity figure.
2. Compare the stated capacity with the outer size, and drop any figure that is larger than the outer box.
3. Check that the planter has a hole in the base, a removable tray or a drain plug.
4. Measure the space you have, including the rail or the walkway, and check the width against the number of planters you want.
5. Plan for the weight of a full planter. The item weights in the listings are for the empty product, and none of the listings gives the weight of a filled planter.

How we chose

Each listing had to describe a planter that a buyer could place on a patio, balcony, rail or bed. It had to state a size that could fit that space. It had to state drainage holes, a tray or a drain plug, or give enough figures to check the drainage question. And it had to give at least one capacity or size figure that could be checked against the others. We read the title, the bullets and the stated specifications for each of the 12 listings in the local data for this keyword, which was checked on 20 October 2026.

Ten listings passed and became cards. Each card’s reason comes from its own listing: a stated capacity, a size, a depth, a tray, wheels or a number of levels. The cards appear in the order of the data and do not rank the planters.

We did not use any sales or feedback signal, because the local data for this guide has none. Affordability is therefore assessed only by the method in this guide, and not by any figure from the listings.

What we could not verify

• Which planter is the cheapest. The local data holds no prices, so this guide cannot name a lowest price, and it does not claim that any planter here is affordable.
• Soil volume for most listings. Only some listings state a capacity, and several of those figures do not match their outer size.
• Durability. The listings describe weather-resistant, rust-resistant, UV-resistant or fade-resistant materials. The pages we opened do not test those claims for plastic, galvanized steel or resin.
• Load limits. None of the listings gives a load limit for the planter filled with soil.
• Filled weight. The listed weights are for empty products, and none gives a figure for a planter filled with soil.
• The capacity of the FOLLOOK and Generic planters. The figures are larger than, or far above, their outer boxes, and the listings do not explain the gap.
• The round shape of the VEVOR bed. Its listed capacity is a rounded figure for a round box, and the listing does not give a soil volume.

Listings without a card: Two listings in the local data did not get a card, because neither is a planter. The Alickwang winter cover for a raised garden bed is a fabric cover that protects a bed, and it does not hold soil. The iBorn deck hook is a wrought iron hook for a railing, meant for hanging a feeder or a planter, and it holds nothing itself. We did not use either one.

FAQ

Can you tell which planter is cheapest from this guide?

No. The listing data has no prices, so this guide cannot name a cheapest planter. It can tell you how to find the cheapest per gallon of soil: look up the price on the product page, convert the stated capacity to gallons, and divide.

Do affordable planters need drainage holes?

Yes, if they are going to hold soil and plants for long. The University of Maryland container page says all containers need adequate holes or slits to drain excess water. A planter without a hole and without a removable tray is a poor choice at any price.

Is gravel in the bottom a cheap way to improve drainage?

No, and it does not help. The Illinois Extension page calls the gravel idea a myth, and the University of Maryland container page says rocks, gravel or broken pot shards will not improve drainage. A hole in the base or a drain plug does the work that the gravel was supposed to do.

Why does the capacity figure matter more than the size?

The size tells you the outer box, and the capacity tells you what the box holds. The two can differ a lot. In this set, the Elevon figure equals its outer box, which leaves no room for walls, and the FOLLOOK figure is larger than its outer box. Use the capacity only where it is a plausible share of the size.

How deep should a planter be for vegetables?

The Iowa State potting media article says plants that need excellent drainage can be easier to care for in taller pots than in shorter ones. The listings give overall heights rather than soil depths, so use the stated heights as a rough guide. Among the beds, the TDDSS bed is the tallest at 17.3 inches, and the Generic tier is 14.5 inches. The small pots suit herbs better than root vegetables.

Bottom line

Do not start with the price, because the listing data cannot rank planters by it. Start with the stated capacity, check it against the outer size, confirm the drainage, and then divide the price you see by the gallons the planter can really hold. That is how to find an affordable planter in the sense that matters for soil.
