5ft vs 6ft vs 7ft Barbell: Which Length to Get

For 1 inch standard bars like ours, get the 7 ft if you will rack it; otherwise the 6 ft does most jobs and the 5 ft suits the tightest rooms. Our Signature Fitness bars measured 60, 70 15/16 and 84 in long, with 9 1/16, 13 1/8 and 15 1/8 in of plate space per side (our preliminary check, tape and bathroom scale, 2 Oct 2026, not a Ledger entry). Some 6 ft Olympic bars do rack.

Length decides three things: whether the bar racks, how much floor you need to load it, and how much room there is for plates on each end. This guide compares the three Signature Fitness 1 inch standard bars we sell on each of those, from our own tape and scale figures, and works out on paper how many plates would fit per side from the thicknesses York Barbell lists. Comparing 2 inch Olympic bars instead? Their numbers follow a different pattern; see Olympic bars.

The three lengths side by side

Measured: our preliminary check, tape and bathroom scale, 2 Oct 2026, not a Ledger entry. Each weight is one bathroom scale reading. The between-collar figure is the length minus both plate spaces, so it runs to the collars' outer faces; the gap inside the collars is still pending. The last two rows apply the rules of our length guide's checker, explained under Room and rack below.

The 6 ft is shorter than its name: ours taped at 70 15/16 in, 1 1/16 in under a full 72 in and close to the 70.67 in on the maker's own drawing (our preliminary check, tape and bathroom scale, 2 Oct 2026, not a Ledger entry). Plan a room around the measured figure, not the name. How we measure shows how these figures were taken.

What each step up in length buys you

The extra length does not go to the same place each time. From 5 to 6 ft, most of it goes to the sleeves, where the plates load. From 6 to 7 ft, most of it goes between the collars, and that wider span is what lets the 7 ft rack.

Differences between the measured figures above, so the same label applies: our preliminary check, tape and bathroom scale, 2 Oct 2026, not a Ledger entry. The between-collar change is derived the same way, to the collars' outer faces.

So if plate room is why you want a longer bar, the 6 ft gives you most of it: 4 1/16 in more per side than the 5 ft, against 2 in more for the step on to the 7 ft (our preliminary check, tape and bathroom scale, 2 Oct 2026, not a Ledger entry). If racking is the reason, only the 7 ft spreads its collars wide enough for a rack built for a 7 ft Olympic bar.

How many plates fit on each side

Plates load from the fixed inner collar to the end of the bar, so the plate space sets how many fit, and plate thickness varies by brand and style. York Barbell lists thicknesses for its plates in two 1 inch lines: Flat Pro, its thin "pancake" plates, and Contour, its thicker ones. Here is how many of each would fit per side of our bars on paper, before you add an outer collar.

Up to about this many per side, on paper, before an outer collar. Each count is the bar's plate space per side, less 1/16 in for our tape's precision, divided by the thickness York lists, rounded down. Six of the fifteen counts leave 1/16 in or less to spare after that allowance (on the 5 ft, the 3/4, 1 and 1 1/8 in plates; on the 6 ft, the 1 in; on the 7 ft, the 3/4 and 1 in), so a plate even slightly thicker than listed takes each of those down by one. We have not test-fitted York plates on these bars, and our own plate and collar fit test is still pending. Plate space: our preliminary check, tape and bathroom scale, 2 Oct 2026, not a Ledger entry. Thicknesses: York Barbell's product pages, checked 2 Nov 2026.

Real loads mix sizes. A 25, a 10 and a 5 lb plate on each side, 80 lb of plates in all, take 2 3/4 in of each sleeve in York's Flat Pro line and 3 3/8 in in its Contour line, by York's listed thicknesses. On the 5 ft, with 9 1/16 in of plate space per side (our preliminary check, tape and bathroom scale, 2 Oct 2026, not a Ledger entry), that is about a third of each sleeve, so at loads like that the sleeve is not what limits a 1 inch bar. Room on the sleeve is not strength: a full sleeve of 25s would be hundreds of pounds, and we print no weight rating for these bars because we have not verified one. Check the rating of any bar before you load it, and lock every plate with a collar. Your plates may be thicker or thinner than York's, so stack yours and measure the stack before you buy more. To plan a load, the plate calculator counts the bar and names the plates for each side.

Room and rack: what each length fits

Room. You stand at the bar and slide plates onto each end, so our rule of thumb is the bar's length plus about a foot on each side: about 7 ft of clear width for the 5 ft, 8 ft for the 6 ft and 9 ft for the 7 ft. It is the same rule the checker in our barbell length guide uses. Measure the clear width where you will load the bar, wall to wall or wall to furniture, and pick the longest bar that fits it with that foot to spare on each end.

Rack. A bar racks when the gap between its collars is wider than the outside of your uprights, so the collars clear them and the shaft sits in the J-cups. On our bars the collars' outer faces sit about 41 7/8 in, 44 11/16 in and 53 3/4 in apart on the 5, 6 and 7 ft (derived from our preliminary check, tape and bathroom scale, 2 Oct 2026, not a Ledger entry). The gap inside the collars is a little less and still pending, so the checker asks a 1 inch bar for 1 1/2 in of margin: uprights up to about 40 3/8 in across the outside for the 5 ft, 43 3/16 in for the 6 ft and 52 1/4 in for the 7 ft. A rack built for a 7 ft Olympic bar has to seat the IWF men's bar, which has 131 cm, about 51.6 in, of shaft between its sleeves, so our 7 ft should clear it too. The 5 and 6 ft need narrower stands. Measure your uprights outside to outside before you count on racking any of them, or run the width through the checker in its 1 inch mode.

Who each length suits

Each length's case comes from what its step adds, in the table above.

The 5 ft is for when floor width is the limit. It needs about a foot less clear width to load than the 6 ft and is the lightest of the three to lift down and store. The cost is plate room, the least of the three per side, and collars set close enough together that it racks only on narrow stands.

The 6 ft gets most of the extra plate room for the least extra length. Over the 5 ft it adds 4 1/16 in of plate space per side for 10 15/16 in more bar, while the step on to the 7 ft adds only 2 in more per side (our preliminary check, tape and bathroom scale, 2 Oct 2026, not a Ledger entry). Its collars sit only a little further apart than the 5 ft's, so it still needs narrow stands to rack. It suits a room with about 8 ft of clear width and no rack built for a 7 ft bar.

The 7 ft is for racking. The step from the 6 ft puts most of its extra length between the collars, 9 1/16 in more (our preliminary check, tape and bathroom scale, 2 Oct 2026, not a Ledger entry), and that is what lets it seat on a rack built for a 7 ft Olympic bar. It also has the most sleeve, though room on the sleeve is not a weight rating. It needs the most room, about 9 ft of clear width, and it is the heaviest of the three.

For all three: if you expect to squat or deadlift heavy within a year, start with a 2 inch Olympic bar instead. Olympic vs standard explains why, and is a 1 inch barbell worth it covers the limits of a standard set.

What length barbell should I get

1. Will you rack it? Get the 7 ft, the only one of our three wide enough between its collars for a rack built for a 7 ft Olympic bar. The 5 and 6 ft rack only on narrow stands.
2. No rack, and about 8 ft of clear width? Get the 6 ft. It does most jobs and has most of the 7 ft's plate room.
3. Less room than that? Get the 5 ft, which needs about 7 ft of clear width.
4. Want the most room for plates? The 7 ft has the most sleeve, but room is not a weight rating, and we print none for these bars. If your loads will keep climbing, a 2 inch Olympic bar is the better buy.

If you are comparing 2 inch Olympic bars

Olympic bars do not follow our bars' pattern, and short ones differ by maker: Titan Fitness lists its 72.75 in Shorty bar with 54.25 in between its sleeves, wider than the 131 cm, about 51.6 in, of the IWF men's bar, so a 6 ft Olympic bar like it can rack where our 6 ft cannot, while Titan says its 60 in Olympic bar may not fit standard power racks. Check your own bar's sleeve to sleeve figure with the checker in the barbell length guide, which covers the IWF bar and two of Titan's short bars.
