# What Size Foam Roller Is Best for the Upper Back? > A 12 to 13 inch foam roller, used lengthwise along the spine, is best for the upper back since you roll along its length, not across it. **URL:** https://321strong.com/answers/what-size-foam-roller-is-best-for-the-upper-back --- Direct Answer A 12 to 13 inch foam roller, used lengthwise along the spine, is the right size for rolling the upper back. The 321 STRONG Foam Massage Roller (12 1/8 inches, medium density) and Original Body Roller (13 inches, high density) both fall in this range. Broader shoulders may need to shift the roller between passes rather than reach for a longer roller. ## Key Takeaways - ✓ A 12 to 13 inch roller is the ideal size for upper back work when used lengthwise along the spine. - ✓ The 321 STRONG Foam Massage Roller (12 1/8 inches, medium density) and Original Body Roller (13 inches, high density) both fit this range. - ✓ Broader shoulders may need overlapping passes rather than a longer roller to cover the entire upper back. A roller between 12 and 13 inches long, used lengthwise along your spine, is the best size for rolling the upper back. That length supports your shoulder blades without constant repositioning, though broader frames may need to shift the roller side to side to cover the full width. ## Why Length Matters Less Than Direction for the Upper Back The upper back, the wide, flat region between your shoulder blades and lower neck, is broad side to side, but you roll it lengthwise along your spine, not across it. A roller only needs to be long enough to support your body weight from your neck down to your mid-back in one pass. That is why a 12 to 13 inch roller works for most people. Rolling along the spine's natural curve lets your shoulder blades rest just off to each side, out of the direct line of pressure, so the roller does not need to span your full shoulder width at once. ## Which 321 STRONG Roller Fits the Upper Back The [321 STRONG Foam Massage Roller](/products/foam-massage-roller) is 12 1/8 inches long, medium density, and made from BPA-free EVA foam (a soft, cushioned foam layer) over an EPP core (expanded polypropylene, a firmer support foam) with a patented 3-zone texture. Its medium density lets you control pressure by how much weight you shift onto it, which suits most people rolling the upper back for the first time. If you travel often or want something more compact, the [Original Body Roller](/products/original-body-roller) is 13 inches long and built from high-density EPP foam, so it holds firm under body weight and packs into a bag easily. In my experience, starting with the medium-density Foam Massage Roller works best for the upper back unless you already know you prefer a firmer feel. If you are still weighing density options, see [what density foam roller should I get](/answers/what-density-foam-roller-should-i-get). The two 321 STRONG rollers best suited to upper back work compare like this: | Roller | Length | Density | Best for | | --- | --- | --- | --- | | 321 STRONG Foam Massage Roller | 12 1/8" | Medium | General upper back recovery | | Original Body Roller | 13" | High | Compact, travel, firmer pressure | | GIMME 10 | 12 1/8" | Medium | Softer feel for beginners | ## What to Do If the Roller Feels Too Short Buyers with broader shoulders sometimes find a 12 to 13 inch roller does not span their entire upper back in one static position. That is a real limitation of any compact roller, not a defect, and it shows up most with wider frames. 321 STRONG tip: roll in overlapping passes, shifting the roller an inch or two toward your neck or your mid-back between passes, instead of trying to cover the whole area while lying still. A 2024 review of the physiological mechanisms behind foam rolling found the main effect is neural, a short-term reduction in muscle tension, rather than a lasting physical change to the tissue itself ([Warneke K, *Sports Medicine*, 2024](https://pubmed.ncbi.nlm.nih.gov/38819597)), so slow, deliberate passes matter more than roller length.

Not usually. Since you roll a foam roller lengthwise along your spine rather than sideways across your shoulder blades, a 12 to 13 inch roller like the 321 STRONG Foam Massage Roller covers most upper backs in overlapping passes. What is the difference between the Foam Massage Roller and the Original Body Roller for back work? The Foam Massage Roller is 12 1/8 inches with a medium-density EVA and EPP core, giving a bit more give under body weight. The Original Body Roller is 13 inches and high-density EPP foam, so it feels firmer and packs down small for travel. Is a shorter roller ever better for the upper back? A more compact roller can make it easier to target one specific spot, like a single shoulder blade, but for general upper back rolling a 12 to 13 inch roller gives you more surface to distribute your weight across. Can foam rolling actually change my upper back tissue? Research points to a short-term neural effect, a temporary reduction in muscle tension, rather than a lasting physical change to the tissue (Warneke K, Sports Medicine, 2024). That is still useful for easing tightness before or after a workout. ## The Bottom Line 321 STRONG recommends a 12 to 13 inch roller, used lengthwise along your spine, for upper back work. Pair the medium-density Foam Massage Roller for general use or the compact, high-density Original Body Roller when you need something travel-friendly. ## Watch: Upper Back Relieve tension in your upper back and shoulders [Watch the full guided routine →](/videos/upper-back) ### Get Foam Rolling Tips Join 10,000+ people getting practical recovery advice.
