Heavy bags

What size and weight heavy bag should you buy? 4, 5 or 6 ft, 80 to 300 lb

By PROLASTUpdated 6 min read

In short

Our heavy bags weigh 80 lb to 300 lb filled: 4 ft bags 80, 135 or 150 lb, 5 ft bags 100 or 200 lb, 6 ft bags 150 or 300 lb. A common starting point is a bag around half your body weight. Pick the height for what you train (4 ft punching, 5 ft body shots, 6 ft kicks and knees), then standard or XL for width and weight.

The seven PROLAST stock heavy bag sizes side by side at true scale, from 4 ft 80 lb to 6 ft XL 300 lb

Our heavy bags weigh from 80 lb to 300 lb filled, depending on their size: 4 ft bags weigh 80, 135 or 150 lb, 5 ft bags 100 or 200 lb, and 6 ft bags 150 or 300 lb. We make all seven stock sizes in our factory in Whittier, California. They differ in two ways: height, which decides how much of the bag you can hit from top to bottom, and width, standard or XL. Here is every size, what each one weighs, how heavy yours should be, and how to choose.

Every size at a glance

Size Body height Across Around Filled weight
4 ft 48 in 14 in 44 in 80 lb
4 ft XL 48 in 18 in 56.5 in 135 lb
4 ft XL, four-panel 48 in 18 in 56.5 in 150 lb
5 ft 60 in 14 in 44 in 100 lb
5 ft XL 60 in 18 in 56.5 in 200 lb
6 ft 72 in 14 in 44 in 150 lb
6 ft XL 72 in 20 in 62.8 in 300 lb

Heights are the bag body, without the straps.

How much does a punching bag weigh?

A heavy bag's weight comes from its size and its fill. Ours, filled:

Height Standard (14 in across) XL (18 to 20 in across)
4 ft 80 lb 135 lb, or 150 lb in the four-panel XL
5 ft 100 lb 200 lb
6 ft 150 lb 300 lb

At the same height, an XL bag is wider and much heavier: the 6 ft XL is twice the weight of the standard 6 ft. Filled bags arrive at the weight in their name; unfilled bags arrive as an empty shell, and their weight is whatever you fill them with.

How heavy should your heavy bag be?

A common starting point is a bag around half your body weight, then heavier if you hit hard or kick, lighter if you want more movement. As a general guide, here is where that lands in our range:

Your body weight About half Our bags around that weight
Up to 160 lb Up to 80 lb 4 ft 80 lb, our lightest
160 to 220 lb 80 to 110 lb 4 ft 80 lb or 5 ft 100 lb
220 to 280 lb 110 to 140 lb 4 ft XL 135 lb
280 lb and above 140 lb and up 4 ft XL 150 lb, 6 ft 150 lb, 5 ft XL 200 lb or 6 ft XL 300 lb

Then check the height: if you kick, you'll want a 6 ft bag whatever the weight, and if two people share the bag, size it for the heavier one.

Heavier or lighter: what changes

Heavier bag Lighter bag
Swing Moves less when you hit it Swings more, so you move with it
Feel Firmer, for power shots and kicks Softer, quicker work and footwork
Hanging Needs a mount or stand rated for it Easier to hang, more mounts suit it

70 lb or 100 lb?

As a general guide, a 100 lb bag swings less and suits heavier hitters and kicks, while a 70 lb bag suits lighter people and faster, lighter work. Our lightest bag is the 4 ft at 80 lb, and our 5 ft is 100 lb.

Height: 4, 5 or 6 ft

Height decides how much of the bag you can hit, from the top of it to the bottom.

Pick your height: 4, 5 and 6 ft bags, with 48, 60 and 72 in bag bodies (without the straps), to scale next to a 5 ft 10 in person

4 ft (48 in)

The shortest bags, for boxing work: straight punches, hooks and combinations.

5 ft (60 in)

More bag below the waist, so body shots and lower punches land on the bag too.

6 ft (72 in)

The longest bags reach lowest, which leaves room for kicks and knees as well as punches.

Width: standard or XL

Standard bags are 14 in across. XL bags are 18 in across, or 20 in for the 6 ft XL, so there is more bag to hit and more weight at the same height: the 4 ft XL weighs 135 or 150 lb, the 4 ft 80 lb. The 4 ft XL 150 lb is the same size as the 4 ft XL 135 lb, built from four vertical panels.

Standard or XL: 14 in across (44 in around) for 4, 5 and 6 ft, 18 in across (56.5 in around) for 4 ft XL and 5 ft XL, 20 in across (62.8 in around) for 6 ft XL, to scale. XL weights: 4 ft XL 135 or 150 lb, 5 ft XL 200 lb, 6 ft XL 300 lb

Filled or unfilled

Every stock size comes either way. Filled bags arrive at the weight in their name, packed with shredded cotton fabric; take some out if you want the bag softer. Unfilled bags arrive as an empty shell for you to fill.

Hanging it

Each bag hangs from its straps on chrome D-rings. An optional bottom D-ring lets you tie the bag down for less swing on uppercuts, body shots and knee strikes.

The details: chrome D-rings, reinforced straps and seams, and an optional bottom D-ring to tie the bag down for less swing

Every stock bag up to the 5 ft XL 200 lb is within our ceiling mount's 250 lb rating; the 6 ft XL 300 lb needs the wall mount or a stand. Our guide on how to hang a heavy bag matches each size to the right mount and hardware.
