Capacity varies by size, style, and the surface you mount into. On our site, many small screw-in cup hooks (around 7/8 in.) list about 0.5 lb, while some mid-size options (around 1-1/4 in.) list about 1 lb. Large suction cup hooks often list up to 5 lb on smooth, non-porous surfaces.

• Mounting matters: Solid wood or a ceiling joist typically supports more than drywall.
• Surface and conditions: Humidity and temperature can reduce holding power, especially for suction cups.
• Check the product page: Look for the posted weight rating and stay under it for a safety margin.

When in doubt, distribute weight across multiple hooks.

Pre-drilling isn’t always required, but it can make installation cleaner and more secure—especially in hardwoods, cabinets, or when placing ceiling hooks for plants.

1. Mark the spot and use a bit slightly smaller than the screw’s shank (not the threads).
2. Drill a pilot hole straight and to a depth close to the threaded portion.
3. Twist the hook in by hand; if needed, use pliers over a cloth to protect the finish.

• Softwood: You may start without a pilot, but pre-drilling helps prevent splitting.
• Drywall: Consider hitting a stud or using an appropriate wall anchor.
• Safety: Avoid drilling where electrical or plumbing may run.

On glazed tile, the strongest options typically combine a clear weight rating with a secure attachment design and a smooth, clean surface.

• Weight rating: Look for a stated capacity; some larger cups list up to 5 lb.
• Surface: Works best on smooth, non-porous tile—avoid grout lines or textured areas.
• Attachment style: Lever-lock or twist-to-lock designs can improve hold versus simple press-on styles.
• Materials: Stainless-steel hooks resist corrosion in humid bathrooms.
• Setup: Clean the tile with alcohol, dry completely, press firmly, and recheck periodically. Giving the cup time to settle can help.

You can use filters on the category page to compare capacities and finishes.

Sizes on our site appear as measurements like 7/8 in., 1-1/4 in., or 2-1/4 in. How brands define that size can vary—some reference overall length, while others may highlight hook opening or screw length.

• Check the product specs: Look for dimensions that list overall length, screw length, and the hook opening.
• Match to your item: Choose a hook with an opening larger than the thickest part of what you’re hanging (e.g., mug handle or cable bundle).
• Unsure? Assortment packs offer multiple sizes so you can test fit.

Use on-page filters to compare sizes, finishes, and pack counts quickly.

Yes—just choose styles and finishes suited for the elements and mount them on appropriate surfaces.

• Finishes: Corrosion-resistant options like stainless steel, brass, or vinyl-coated hooks are commonly used outdoors.
• Mounting: For plants or string lights, screw into solid wood (e.g., eaves or joists) for better support. Outdoor conditions can reduce capacity, so stay under the rated load.
• Suction cups: They can work on clean glass doors or windows; temperature swings and moisture may affect hold, so re-seat as needed.
• Care: Keep surfaces clean and periodically check tightness.
