1. NUMENN 6 Tier Bookshelf, Tall Freestanding Open Storage Bookcase, Grey — Smallest listed footprint

Listed details: dimensions 11.8″ D × 23.6″ W × 66.5″ H; material Alloy Steel, FSC-certified wood panels; color Grey.

The NUMENN 6 Tier Bookshelf is a grey freestanding open bookcase listed at 11.8 in deep, 23.6 in wide and 66.5 in high, or 1.93 sq ft, the smallest footprint of the three. The spec table lists alloy steel with FSC-certified wood panels, while a bullet calls the panels particle board. It has 6 shelves, and the listing says installation takes eight steps with detailed instructions and tools included, and tells you to install the anti-tilt hardware. The listing does not state an item weight or a weight capacity per shelf.

Pros

• Smallest footprint at 1.93 sq ft, and the shortest at 66.5 in.
• The listing tells you to install the anti-tilt hardware, so tip safety is addressed.
• Eight installation steps with instructions and tools included.

Cons

• The listing calls the panels FSC-certified wood in the specs and particle board in a bullet, so the real material is unclear.
• No item weight and no per-shelf weight capacity are stated.
• All six shelves are open and none is described as adjustable, so items stay on view and heights are fixed.

Who it is for / who should skip it: Pick it if you want the smallest footprint with six open shelves and stated anti-tilt hardware. Skip it if you want doors or adjustable shelves.

2. TVU Bookshelf and Bookcase with Doors, 5 Open Shelves & 2 Door Storage Cabinet, 77.2″ Tall Freestanding Book Shelf for Living Room, Home Office, Bedroom, Grey — Largest listed footprint

Listed details: dimensions 10.1″ D × 31.5″ W × 77.2″ H; material Wood; color Grey.

The TVU Bookshelf and Bookcase with Doors is a grey classic-style freestanding unit listed at 10.1 in deep, 31.5 in wide and 77.2 in high, or 2.21 sq ft, the largest footprint of the three. The listing describes 5 open shelves and 2 closed storage layers behind doors, which the spec table counts as 7 shelves. It says the uprights are New Zealand pine, the hinges are waterproof metal and the base is arched. Detailed instructions and installation numbers are included.

Pros

• Two closed layers behind doors hide clutter, which neither other bookcase offers.
• Tallest and widest, 77.2 in high and 31.5 in wide, so it holds the most (10.7 in taller than NUMENN).
• Uprights are described as New Zealand pine, and the hinges as waterproof metal.

Cons

• Largest footprint at 2.21 sq ft, 0.28 sq ft more than NUMENN (2.21 – 1.93).
• At 77.2 in tall it needs wall anchoring, and the data shown does not mention any anti-tip hardware.
• No item weight or weight capacity per shelf is stated.

Who it is for / who should skip it: Pick it if you want closed storage and the most capacity and have about 31.5 in of wall. Skip it if you have a low ceiling or narrow gap.

3. HCHQHS Bookshelf, Adjustable Industrial Bookcase, Vertical Tall Book Shelf, Wood and Black Metal Open Bookshelves for Home Office, Living Room, Bedroom (Grey, 6-Tier (31″ W x 70″ H)) — Middle listed footprint

Listed details: dimensions 12″ D × 24″ W × 70″ H; item weight 43 pounds; material Engineered Wood, Metal; color Grey.

The HCHQHS Bookshelf is a grey industrial bookcase in engineered wood and black metal, listed at 12 in deep, 24 in wide and 70 in high, or 2.0 sq ft, the middle footprint of the three. The spec table gives 43 pounds and 6 shelves, but a bullet calls it a 5 tier bookshelf, so confirm the count. The listing says the middle shelves are adjustable, that it has 8 storage hooks, and that the MDF meets the US CARB P2 standard. Numbered parts and instructions are included. The listing does not state a weight capacity per shelf.

Pros

• The middle shelves are listed as adjustable, which neither other bookcase states.
• Eight storage hooks are listed, and the listing gives a 43 pound item weight.
• The MDF is stated to meet the US CARB P2 standard.

Cons

• The spec table says 6 shelves while a bullet says 5 tier, so the count is unclear.
• Deepest at 12 in, 1.9 in more than the TVU bookcase (12 – 10.1), so it takes more room out from the wall.
• No per-shelf weight capacity is stated, and the black metal industrial look may not suit every room.

Who it is for / who should skip it: Pick it if you want adjustable shelves and hooks and will confirm the shelf count. Skip it if you want doors or the smallest footprint.

What to check before buying grey bookcase

A grey bookcase comes down to footprint, height and how the shelves are set up. First, footprint. The three come to 1.93, 2.0 and 2.21 sq ft, a spread of 0.28 sq ft, with widths of 23.6 in, 24 in and 31.5 in. Second, height and tip safety. The listed heights are 66.5 in, 70 in and 77.2 in. The NUMENN listing tells you to install the anti-tilt hardware. The data shown for TVU and HCHQHS does not mention anti-tip hardware, so plan to anchor a tall unit to the wall yourself. Third, open or closed storage. TVU has 5 open shelves and 2 closed layers behind doors, and the other two are fully open. Fourth, adjustability. Only HCHQHS says its middle shelves are adjustable, so check that against the tallest items you own. Fifth, capacity and weight. None of the three states a per-shelf limit. HCHQHS states 43 pounds for the whole piece and the other two state no weight. Sixth, material. NUMENN is listed as alloy steel with FSC-certified wood panels in the specs but particle board in a bullet. TVU lists pine uprights. HCHQHS lists MDF that meets US CARB P2. Seventh, shelf count. HCHQHS lists 6 shelves in the specs and 5 tier in a bullet, and TVU’s 7 counts its closed layers. Confirm before you plan.

Worked example: fit math for these three options

This worked example is our own planning arithmetic from the listed dimensions, not test results. The wall length and walkway width are assumed example values; replace them with your measurements.

Wall example. Assume 48 inches of clear wall.

• NUMENN 6 Tier Bookshelf: 48 − 23.6 = 24.4 inches spare; centred, 12.2 inches on each side before trim, plugs or curtains.
• TVU Bookshelf and Bookcase with Doors: 48 − 31.5 = 16.5 inches spare; centred, 8.25 inches on each side before trim, plugs or curtains.
• HCHQHS Bookshelf: 48 − 24 = 24 inches spare; centred, 12 inches on each side before trim, plugs or curtains.

Walkway example. The US Access Board gives 36 inches as the minimum clear width for an accessible route. That figure is a yardstick, not a rule for private homes. To keep 36 inches clear beside each product, the walkway between it and the opposite obstacle must be at least 36 inches plus its depth:

• NUMENN 6 Tier Bookshelf: 36 + 11.8 = 47.8 inches of total path width.
• TVU Bookshelf and Bookcase with Doors: 36 + 10.1 = 46.1 inches of total path width.
• HCHQHS Bookshelf: 36 + 12 = 48 inches of total path width.

Footprint. Depth × width, converted at 144 square inches per square foot:

• NUMENN 6 Tier Bookshelf: 11.8 × 23.6 = 278.48 sq in, or 1.93 sq ft.
• TVU Bookshelf and Bookcase with Doors: 10.1 × 31.5 = 318.15 sq in, or 2.21 sq ft.
• HCHQHS Bookshelf: 12 × 24 = 288 sq in, or 2 sq ft.

Mistakes to avoid

• Skipping the anchor. Heights run from 66.5 in to 77.2 in, and only the NUMENN listing tells you to install anti-tilt hardware. Anchor any tall bookcase.
• Trusting the shelf count. HCHQHS says 6 shelves in the specs and 5 tier in a bullet. TVU’s 7 includes two closed layers behind doors.
• Assuming a per-shelf limit. None of the listings states one, so ask the seller before loading shelves with heavy books.
• Ignoring depth. The depths are 10.1 in, 11.8 in and 12 in, so measure your largest books and the clearance behind doors or furniture.

Frequently asked questions

Which grey bookcase has the smallest footprint?

The NUMENN listing comes to 1.93 sq ft (11.8 in deep by 23.6 in wide), compared with 2.0 sq ft for HCHQHS and 2.21 sq ft for TVU. NUMENN is also the shortest at 66.5 in. The TVU is the tallest at 77.2 in.

Do these bookcases need to be anchored?

The TVU and HCHQHS data shown does not mention anti-tip hardware. All three are at least 66.5 in tall, so securing them to the wall is a sensible precaution.

Do any of them have doors?

Only the TVU bookcase. Its listing describes 5 open shelves and 2 closed storage layers behind doors, with waterproof metal hinges. The NUMENN and HCHQHS bookcases are open, so everything on the shelves stays visible.

Can I adjust the shelf heights?

The HCHQHS listing says the middle shelves are adjustable. The NUMENN and TVU listings do not say that in the data shown, so assume their shelf heights are fixed unless the seller confirms otherwise.
