Samsung’s refurbished lineup spans 6.1 to 7.6 inches across four distinct form factors: standard slabs, Plus models, Ultra flagships, and foldables.
The right size depends less on raw dimensions and more on how you use your phone.
Here’s how every key refurbished model stacks up.

Samsung Refurbished Phone Sizes: The Full Comparison
Here’s a quick-reference table covering every current-generation Samsung model worth buying refurbished.
Anything older than the S21 series has been excluded because of short software support windows which make them a poor investment.
| Model | Screen Size | Dimensions | Form Factor |
|---|---|---|---|
| Galaxy S24 | 6.2″ | 147.0 x 70.6 x 7.6mm | Standard |
| Galaxy S24+ | 6.7″ | 158.5 x 75.9 x 7.7mm | Plus |
| Galaxy S24 Ultra | 6.8″ | 162.3 x 79.0 x 8.6mm | Ultra |
| Galaxy S23 | 6.1″ | 146.3 x 70.9 x 7.6mm | Standard |

| Galaxy S22 Ultra | 6.8″ | 163.3 x 77.9 x 8.9mm | Ultra |
| Galaxy S22 | 6.0″ | 146.0 x 70.6 x 7.6mm | Standard |

Which Refurbished Samsung Size Is Right For You?
The One-Handed Camp: Galaxy S23 or S24 (6.1–6.2″)
The Galaxy S24 in Marble Grey or Onyx Black is the sweet spot for anyone who finds most modern phones unwieldy. At 147mm tall and just 70.6mm wide, it’s one of the most pocketable flagships on the market — and the Snapdragon 8 Gen 3 chip means it won’t feel dated for years.
The Galaxy S23 in Lavender or Green goes even more compact at 6.1 inches. If budget is the deciding factor, the S23 series is the value sweet spot in Samsung’s refurbished lineup — four years of OS updates remaining (from Android 13), solid cameras, and prices that undercut the S24 by a meaningful margin.
Best for: Commuters, one-handed typists, smaller hands, budget-conscious buyers.
The Mainstream Middle: Galaxy S24+ (6.7″)
Most people actually land here. The S24+ hits the exact centre of the size spectrum, meaning its big enough for comfortable media consumption and small enough to use without two hands most of the time.
It’s the model Samsung sells the most of for good reason.
Best for: All-rounders who watch video, scroll social feeds, and want a bit more battery headroom without going full Ultra.
The Power User: Galaxy S24 Ultra or S23 Ultra (6.8″)
These are big phones. At 162–163mm tall and 78–79mm wide, the Ultra models demand two hands.
What you get in return is Samsung’s best camera hardware: a 200MP primary sensor on the S24 Ultra, 10x optical zoom, and built-in S-Pen support that turns the phone into a pocket notebook.
The Galaxy S23 Ultra in Phantom Black or Lavender is the more financially sensible route right now. S23 Ultra units have softened significantly in refurbished price while still delivering every hardware capability that made it exceptional at launch. The S22 Ultra in Green goes even cheaper, though with a shorter software runway — factor that in before buying.
For creators shooting YouTube or TikTok content, the Ultra’s versatile camera system is hard to argue with — our guide to the best used phones for content creators puts the Ultra range in proper context alongside the iPhone’s video capabilities.
Best for: Photography enthusiasts, note-takers, power users who want maximum capability.
The Foldable Case: Galaxy Z Fold 5 or Z Fold 4 (7.6″ unfolded)
Foldables are genuinely useful tools, not gimmicks — but they come with caveats. The Galaxy Z Fold 5 in Phantom Black or Blue unfolds to a 7.6-inch tablet-style display while folding down to a phone that fits in a jacket pocket.
The hinge mechanism on the Fold 5 is the most refined Samsung has produced; its considerably tighter and more durable than the Fold 4, which is reflected in the price gap between them.
The Galaxy Z Fold 4 in Phantom Black makes sense if the budget is tight, but be clear-eyed about the hinge and crease — both are more noticeable on earlier generations.
Best for: Professionals who want a phone-and-tablet in one device; frequent travellers who want to ditch their iPad.
The Novelty Flip: Galaxy Z Flip 4 (6.7″ unfolded, tiny when folded)
The Galaxy Z Flip 4 in Bora Purple is the only Samsung phone that genuinely fits in a jeans pocket when closed — at 85mm tall, it’s compact in a way no standard slab can match. The trade-off is a modest camera system and shorter update support compared to the S series.
Best for: Fashion-forward buyers, those who want a truly small-form device, secondary phone users.
Newest on the Market: Galaxy S25 Series (6.2–6.9″)
The Galaxy S25 in Silver Shadow or Navy and the Galaxy S25 in Mint or Silver Shadow have started to appear in refurbished stock. At 6.2 inches, the standard S25 is almost dimensionally identical to the S24 but with the new Snapdragon 8 Elite chip and seven years of guaranteed OS updates — a significant longevity advantage.
The Galaxy S25 Ultra in Titanium Silverblue represents the current peak of Samsung’s hardware. Its 6.9-inch display is the largest slab screen in the lineup. Worth noting: the S25 Ultra drops the dedicated S-Pen silo and replaces it with optional Bluetooth stylus support — worth checking if the S Pen matters to you before buying.
Best for: Anyone who wants to buy once and hold for five-plus years, early adopters looking for a deal on near-current hardware.

What About the Galaxy A Series?
The A series isn’t in our core refurbished recommendations, with one exception. The Galaxy A55 is the only A-series model we’d point most people toward, and only if budget genuinely rules out an S23.
The older A52, A53, and A54 are on short software support timelines now, and their Exynos chipsets age less gracefully than the Snapdragon-powered S series.

Know Your Mobile Verdict
Size alone shouldn’t drive your Samsung buying decision, software longevity should.
The S24 and S25 series get seven years of updates; the S23 gets four from its 2023 launch.
Buy the smallest model that meets your camera and screen needs, but don’t go older than the S22 series on anything you plan to keep for more than two years.
💡 Pro-Tip: If you’re torn between the S23 Ultra and S24 Ultra on price, check the refurbished condition grade carefully. An S23 Ultra in Grade A condition will outlast and outperform an S24 Ultra in Grade C — the chip difference between generations is far less significant than screen and battery health.
