Yoga Blocks: Five Listings Compared by Size, Material and Pack Count
As an Amazon Associate we earn from qualifying purchases.
A yoga block brings the floor closer to your hand, which makes standing poses and seated stretches easier to hold. Most blocks are a foam brick with a flat top and bottom, but the sizes and densities differ. The listings here are mostly EVA foam in two sizes, with one polypropylene set and one foam block with a different height. This guide reads each one by the measurements and material the listing gives.
Quick answer
Size is the first thing to check. The blocks in this group are close to 9 by 6 inches on the top, but the height ranges from 3 to 4 inches. A taller block lifts the hand higher, which suits a standing pose better than a seated one. Material is the second check. EVA foam is light and grippy in most of these listings, while the Amazon Basics set is polypropylene. Pack count matters if you need two blocks for a single practice.
How we chose
Each entry below uses the product details saved for the listing: the stated dimensions, material, color, item weight, pack count and care line. The guide quotes each detail as the listing gives it and does not describe how any block feels under load or how it wears after months of use. It does not rank the blocks against each other.
What we could not verify
Grip and firmness are not measured here, and the listings describe them in their own terms. Some listings give a number of items that does not match the unit count, and the guide notes those where they occur. Where a material is not stated, the guide leaves it out. Color names are the listing’s names, and the shade on the screen may differ from the block you receive.
The five listings
Amazon Basics: set of two, 4 by 9 by 6 inches, polypropylene, black
The Amazon Basics listing is a set of two blocks, each measuring 4 inches high, 9 inches wide and 6 inches deep. The material is polypropylene, a plastic rather than foam, and the color is black. The listing gives an item weight of 163 grams per block. The care line says to wipe with a dry cloth.The listing asks for a dry wipe. A hard plastic block is easy to clean, but it is less cushioned than a foam block. View the Amazon Basics blocks on Amazon.
Gaiam: one block, 9 by 6 by 4 inches, EVA foam, black
The Gaiam block measures 9 by 6 by 4 inches and is made of ethylene vinyl acetate foam. The color is black and the item weight is 6.4 ounces. The listing describes beveled edges and a non-slip surface, and the care line says to spot clean with mild detergent and towel or air dry.

Trideer: two-pack, 9 by 6 by 3 inches, EVA foam, mint green
The Trideer listing is a pack of two blocks, each 9 by 6 by 3 inches. The material is EVA foam, the color is mint green, and the item weight is 4.23 ounces per block. the listing gives a unit count of two. The care line says to wipe with a damp cloth. The 3-inch height is shorter than the 4-inch blocks in this group, so it sits lower under the hand. View the Trideer two-pack on Amazon.
Gaiam: one block, 9 by 6 by 4 inches, foam, blush
The second Gaiam block is the same 9 by 6 by 4 inch size, in a blush color. The listing describes its material as foam, and gives an item weight of 0.13 kilograms. Cleaning follows the listing: the listing asks for a dry wipe. It matches the black Gaiam block in size, so the two can be used together as a pair if you prefer a different color.

KEEP: two-pack, 5.9 by 9.6 by 3 inches, EVA foam, grey
The KEEP listing is a two-pack of EVA foam blocks in grey. Each block measures 5.9 inches by 9.6 inches by 3 inches, which is a little narrower than the other blocks in this group. The item weight is 7 ounces, and the care line says to wipe with a dry cloth. the unit count is two. A narrower block fits a smaller hand, but it offers less surface for a wide hand placement.

Height is the measurement that changes how a block feels. Three inches sits lower, four inches lifts the hand higher. The width and depth are close across the group, so height is the main difference in size.
Height and reach
A four-inch block gives more lift for standing poses such as triangle and half-moon variations. A three-inch block keeps the hand closer to the floor, which some people prefer for seated work. Choose the height by the poses you practise most, not by the size of the box.
Foam or plastic
EVA foam blocks are light and cushioned, which suits most home practice. The Amazon Basics set is polypropylene, which is harder and easier to wipe clean, but it offers less give under the hand.
Checks to make before you order
Confirm the count. The Gaiam listings are sold as single blocks, while the Trideer and KEEP listings are two-packs.
Check the material on the product page. Not every listing names it in the same way.
Measure the height you want, then compare it with the listing, since two blocks can look alike in a photo.
Which block suits which practice
For a pair for standing poses at home, a four-inch Gaiam block in black or blush is the simplest match, with a second block if you need two. For a seated practice, the three-inch Trideer two-pack sits lower. For a firm surface that wipes clean easily, the Amazon Basics set is the one to compare.
