Count a 9-inch or 4.5-inch wall of the traditional 9 × 4.5 × 3 in brick used in Pakistan and India. Results are bricks, 50 kg cement bags, and sand in cubic meters and CFT (cubic feet), including a per-100-square-foot line and a per-1,000-brick line. How that face compares with the India, UK, and US sizes, with and without the joint, is the brick sizes guide.
Other brick sizes, including the India modular brick, are on the brick calculator. Four walls of a room are on the room calculator. A concrete mix ratio is on the cement, sand, and aggregate calculator.

How the 9-inch wall is counted
The face module is the brick plus a 10 mm joint: 238.6 mm by 86.2 mm. One hundred square feet is 9.290304 m². Two leaves cover that face twice, which is 903.40 bricks, 9.03 per square foot. Five percent waste is only on the brick order: 949. It does not change the mortar.
A 4.5-inch wall is one leaf. Thickness is the brick width, 114.3 mm, and there is no joint through the wall. A 9-inch wall is two leaves plus one collar joint of 10 mm, so the thickness is 238.6 mm, 9.39 inches. Wet mortar is the wall volume minus the solid bricks. Dry mortar is wet times 1.10 times 1.33. A 1:6 mix gives cement 1/7 of that dry volume and sand 6/7.
Per 1,000 bricks
These rows use the same method as the brick calculator. The 4.5-inch row is one leaf. The 9-inch row includes the collar joint. Ratio 1:6, mortar wastage 10 percent, dry factor 1.33, 50 kg bags. The 15.93 CFT is the unrounded 0.45 m³, not 0.45 multiplied out from the rounded figure.
| Wall | Wet mortar | Cement | Bags | Sand |
|---|---|---|---|---|
| 4.5 inch, 1,000 bricks | 0.36 m³ | 0.11 t | 3 | 0.45 m³ · 15.93 CFT |
| 9 inch, 1,000 bricks | 0.46 m³ | 0.14 t | 3 | 0.58 m³ · 20.49 CFT |
Worked example
Leave the length and height at 10 ft, the wall on 9 inch, the joint at 10 mm, brick waste at 5 percent, mortar wastage at 10 percent, and the ratio on 1:6. Bricks read 903.40. The order reads 949. Per square foot reads 9.03. Bricks per 100 ft² read 903.40. Cement reads 0.13 t and bags read 3. Sand reads 0.52 m³ · 18.51 CFT. Sand per 100 ft² is the same, because the wall is 100 square feet.
Frequently asked questions
How many bricks are in 100 square feet of a 9-inch wall?
Leave the wall at 10 ft by 10 ft, which is 100 square feet, and leave the wall on 9 inch. The brick is 9 × 4.5 × 3 in with a 10 mm joint. Bricks in the wall read 903.40, 9.03 per square foot. Five percent brick waste makes the order 949. The per-100-square-foot lines match those figures because the wall is already 100 square feet.
How many bricks are in 100 square feet of a 4.5-inch wall?
Switch the wall to 4.5 inch. The same 100 square feet is one leaf, 114.3 mm thick, with no joint through the wall. Bricks read 451.70, 4.52 per square foot, and the order is 475. Cement is 1 bag of 50 kg. Sand is 0.20 m³, 7.20 CFT.
How much cement and sand does the 9-inch wall need?
The 10 ft by 10 ft 9-inch wall at 1:6, with 10 percent mortar wastage and the 1.33 dry factor, is 0.13 tonnes of cement and 3 bags of 50 kg. Sand is 0.52 m³, which is 18.51 CFT. Wet mortar is 0.42 m³ and dry mortar is 0.61 m³. Cement density is 1,440 kg/m³ and sand is 1,600 kg/m³.
How much mortar is used for 1,000 bricks?
On a 4.5-inch wall the per-1,000 line matches the brick calculator: wet mortar 0.36 m³, dry mortar 0.53 m³, cement 0.11 tonnes, 3 bags, and sand 0.45 m³. That sand is 15.93 CFT. Multiplying the rounded 0.45 m³ by 35.31 prints 15.89, because 15.93 uses the unrounded volume. A 9-inch wall uses more mortar per brick because of the collar joint: 0.46 m³ wet, sand 0.58 m³ (20.49 CFT), cement 0.14 tonnes, and still 3 bags.
Why is a 9-inch wall 9.39 inches thick?
Two leaves of a 4.5 inch brick are 228.6 mm. The collar joint between them is 10 mm, so the wall is 238.6 mm, 9.39 inches. It is not a solid 9 inch block, and there is not a second joint through each brick. A 4.5-inch wall is one leaf, 114.3 mm, with mortar only on the face.
What if the mix is 1:4 instead of 1:6?
Switch the ratio on the 10 ft by 10 ft 9-inch wall. The brick count stays 903.40. Cement becomes 0.18 tonnes and 4 bags of 50 kg. Sand becomes 0.49 m³, 17.28 CFT. The dry mortar is still 0.61 m³. Cement takes a larger share of that same volume.
Does this page include a price?
No. It does not price bricks, cement, or sand. No local rate is cited. The order is bricks, 50 kg bags, and sand in cubic meters and CFT. The India modular 190 × 90 × 90 mm wall stays on the brick calculator. The same 9 × 4.5 × 3 in brick is also sold in India.
