You can buy sandpaper almost anywhere that sells paint, lumber, or auto parts, which makes the choice less about availability and more about matching the right abrasive to the job. Home Depot, Lowe’s, Ace Hardware, Harbor Freight, Menards, Walmart, Northern Tool, Rockler, Woodcraft, Eastwood, and Amazon all stock a deep catalog of sheets, rolls, belts, and discs. This guide narrows the aisle noise to the brands, grit ranges, and retailers that professional finishers and experienced DIYers reach for first when they need an abrasive that actually performs.

The short answer: 3M and Norton sandpaper dominate big-box shelves, Gator and Diablo cover the value tier at Home Depot and Lowe’s, Mirka and Klingspor lead the specialty woodworking channel, and 3M Wetordry rules auto body supply counters. Grit selection matters more than brand for most tasks, so we pair each pick with a grit chart and the closest national retailer that stocks it today.
Shoppers typically fall into one of four buckets: a homeowner grabbing a quick variety pack for a weekend repair, a serious woodworker stocking garnet sheets and ceramic discs by the box, a drywaller buying pole sander rolls, or an auto body DIYer tracking down wet/dry silicon carbide paper above 1000 grit. We cover all four below with verified retailer links.

Where to Buy Sandpaper: Best Sandpaper Retailers Compared
Every general hardware retailer carries basic aluminum oxide sandpaper, but stock depth, grit selection, and specialty formats vary widely. Here is how the major channels compare for anyone shopping in person or online.
Home Depot
Home Depot carries the widest DIY sandpaper selection: 3M, Diablo, Gator, Norton, and Dewalt across sheets, sponges, belts, and hook-and-loop discs. House-brand Gator is the budget anchor. In-store pickup on most SKUs is usually same-day.
Lowe’s
Lowe’s mirrors Home Depot on brand coverage and prices 3M SandBlaster and Norton 3X sandpaper very competitively. Bulk rolls of 80- and 120-grit paper for pole sanders are generally easier to find here than at the other national chains.
Ace Hardware and Menards
Neighborhood Ace stores keep a tighter abrasive range than the big boxes but excel at assorted packs for small repairs. Menards (Midwest) undercuts the national chains on Norton and Gator 5-pack sheets when you catch its 11 percent rebate.
Harbor Freight
Harbor Freight sells Warrior and Bauer sandpaper at the lowest sticker price in the market. Grit accuracy is close enough for rough carpentry and outdoor projects, but pros skip it for fine finishing work where scratch patterns matter.
Amazon
Amazon carries every sandpaper the big boxes stock plus direct-import specialty brands, bulk contractor packs, and harder-to-find extra-fine grits above 1500. Prime shipping closes the gap when the local aisle is picked over or the grit you need is out of stock.
Rockler, Woodcraft, and Klingspor
Specialty woodworking dealers carry Mirka, Klingspor, Festool, and premium garnet sandpaper that the big boxes rarely stock. Expect higher per-sheet pricing in exchange for longer-lasting grain and cleaner cuts on hardwood.
Auto Body Supply: Eastwood and Northern Tool
Eastwood and Northern Tool focus on automotive silicon carbide Wetordry sandpaper, unigrit systems, and DA sander discs. These stores are the shortest path to 1000-, 1500-, 2000-, and 3000-grit paper for paint correction.
Sandpaper Grit Chart: Which Sandpaper Grit for Which Job
Grit number refers to the size of the abrasive particles bonded to the paper backing. Lower numbers are coarser and cut faster; higher numbers are finer and polish. Both CAMI (North American) and FEPA (European, prefixed with P) grit standards appear on sandpaper packaging, so it helps to know how they line up before you buy.
| Grit Range | Category | Best Use |
|---|---|---|
| 40–60 | Coarse | Stripping paint, leveling rough lumber, heavy stock removal |
| 80–120 | Medium | Smoothing framing lumber, shaping wood, removing old finish residue |
| 150–180 | Fine | Final prep for stain, drywall patches, bare wood before primer |
| 220–240 | Very Fine | Between-coat sanding on sealer and paint, light scuff sanding |
| 280–320 | Extra Fine | Polishing oil and lacquer finishes, smoothing knocked-down nibs |
| 400–600 | Super Fine | Wet sanding primer, clear-coat leveling, metal deburring |
| 800–3000+ | Ultra Fine | Automotive paint correction, final polish, mirror finishing |
Sandpaper Types and Grain Materials
Four abrasive grain types cover nearly every project you will tackle. Picking the right grain saves more time than chasing a premium brand at the wrong grit.
Aluminum Oxide
The default all-purpose grain on 3M, Norton, Diablo, and Gator sandpaper. Aluminum oxide fractures slowly and holds up on wood, metal, plastic, and painted surfaces. If you only buy one variety, buy this one.
Garnet
Natural garnet grain is softer and self-renews as it wears, producing a surface that accepts stain more evenly than aluminum oxide. Garnet paper is the traditional woodworker’s choice and still stocked at Klingspor, Woodcraft, and Rockler.
Silicon Carbide
Sharper and harder than aluminum oxide, silicon carbide is the go-to grain for wet sanding, glass, tile, and plastic. 3M Wetordry is the household name and the right abrasive for automotive finishing.
Ceramic
Engineered ceramic grain, used in premium lines from Mirka, Klingspor, and 3M Cubitron, lasts many times longer than aluminum oxide on hardwood and metal. Expect to pay a premium for the longevity this abrasive delivers.
Sheets, Rolls, Discs, and Belts: Choosing a Format
Sandpaper ships in a handful of standard formats sized to common power tools and hand blocks. Buy the format that matches the tool you already own before upgrading the grit number or grain type.
- 9×11 sheets: The universal hand-sanding size; tear into quarters for a sanding block.
- Hook-and-loop discs (5 inch, 6 inch): For random-orbit sanders from Dewalt, Makita, and Festool.
- 1/4 sheet and 1/3 sheet clip-on pads: Fit finishing palm sanders.
- Belts (3×21, 4×24): Benchtop and portable belt sanders.
- Rolls: Long runs on pole sanders for drywall or detail work on contours.
- Sponge blocks: Hand sanding around trim, profiles, and curved edges.
Sandpaper FAQ: Frequently Asked Questions
What grit sandpaper do I need for stripping paint from wood?
Start with 60- or 80-grit aluminum oxide sandpaper to cut through the old finish, then step up to 120 and finally 150 or 180 before staining or priming. Skipping sandpaper grits leaves scratches that show through the new coating.
What is the best sandpaper for drywall?
Use 120- or 150-grit aluminum oxide sandpaper on a pole or hand sander for feathering joint compound, then 220-grit sandpaper for the final light pass. 3M and Norton both sell drywall-specific sandpaper sheets and sponges sized for pole sander heads.
Wet sanding vs dry sanding: when do I use each?
Dry sanding is the default for bare wood, primer, and most paint prep. Wet sanding with silicon carbide sandpaper controls dust, prevents clogging on clear coats, and produces finer scratch patterns above 600 grit, which is why auto body shops rely on wet sandpaper for paint correction work.
When should I replace a sanding sheet?
Replace sandpaper as soon as it stops removing material at a steady rate, even if grain remains on the backing. Dull, glazed sandpaper polishes the surface instead of cutting it and generates heat that can burn wood, so swap sheets often.
What is the difference between garnet and aluminum oxide sandpaper?
Garnet sandpaper uses a softer natural mineral that self-fractures and leaves a warmer, stain-friendly finish on bare wood. Aluminum oxide sandpaper uses a harder synthetic grain that cuts faster and lasts longer across wood, metal, and painted surfaces but can burnish bare hardwood if you push it.
Final Word on Buying Sandpaper Today
For casual home repairs, the Gator and Diablo multi-packs at Home Depot or Lowe’s cover 90 percent of jobs at the lowest cost per sheet. For serious woodworking, step up to Klingspor garnet or Mirka Abranet through Rockler, Woodcraft, or Empire Abrasives. For automotive paint work, 3M Wetordry from Eastwood or Amazon is the industry default. Match your grit to the task using the chart above, and you will get better results from cheap sandpaper than from premium paper at the wrong grit number.
