A CFT calculator for a whole load, not one piece
Most wood calculators do one size at a time. This one is built for the way timber is actually loaded: pick the wood, pick the size, tap each length as the pieces go on the vehicle, and the cubic feet add up line by line and as a running total for the load. What you end up with is a size list - a cutting list - which is simply the timber you need written as sizes: how wide and how thick in inches, how long in feet, and how many pieces. That is all a sawmill needs to quote you.
The volume of each line is worked out the way our own slips do it:
CFT = width (in) × thickness (in) × length (ft) × pieces ÷ 144
The 144 is there because two sides are in inches and one is in feet. If you would rather measure all three sides in inches, divide by 1728 instead - the answer is the same. Each line is rounded down to four decimals, then the lines are added, so the total never reads higher than the timber actually is.

How it works
- Choose the wood - teak, mahogany, manjiyam, or pick Other and tell us in the notes.
- Pick the size - tap a common size (width × thickness), or add your own.
- Tap the lengths - each tap adds a piece. The CFT for that line appears beside it.
- Read the total - pieces and cubic feet for the whole load, at the bottom of the screen.
Nothing here is saved or sent. This is a calculator: the list lives on your own phone and nowhere else, so a lost signal at the loading point does not lose your work, and nobody is asked for a name or a number to use it. You can change the wood or the size at any time from the bar at the bottom without losing what you have counted.
When you want a price for the same sizes, the timber quotation page carries the same sheet with a Send button on it - and gives you a PDF with a reference number to keep.
Working out a lorry load
Loading is rarely one size. A load might be door frame sections in one size, planks in another and battens in a third, in several lengths each. Add them all: the sheet keeps every size separate, shows the CFT per line, and gives you the pieces and the cubic feet for the whole load at the bottom of the screen. Read it out against the vehicle before it leaves, and send the same list to us so the quote and the load are the same document.
Conversions people ask for:
- 1 CFT = 0.0283 CBM (cubic metre); 1 CBM = 35.315 CFT.
- 1 inch = 2.54 cm; 1 foot = 30.48 cm.
- A piece 1 ft × 1 ft × 1 ft is 1 CFT - so 12″ × 12″ × 12″ = 1728 cubic inches = 1 CFT.
Weight is a different question: it depends on the species and how seasoned the timber is, so ask us rather than assuming a figure for your load.
Sizes people ask for most
Useful starting points if you are not sure what to ask for:
| Typically used for | Width × thickness | Length | CFT per piece |
|---|---|---|---|
| Door frame section | 5″ × 3″ | 7 ft | 0.72 |
| Door frame, lighter | 4″ × 2½″ | 7 ft | 0.48 |
| Window frame section | 4″ × 2½″ | 5 ft | 0.34 |
| Plank / board | 6″ × 1″ | 8 ft | 0.33 |
| Cot rail | 4″ × 2″ | 6½ ft | 0.36 |
| Table top plank | 12″ × 2″ | 6 ft | 1.00 |
| Reaper / batten | 2″ × 2″ | 10 ft | 0.27 |

What to do with the total
- Read it out against the vehicle before it leaves - pieces first, then the cubic feet.
- Check it against the rate you were quoted: timber is priced per CFT, so the load total is the figure the bill is built on. What decides that rate.
- Want a price for these sizes? Send the same list from the timber quotation page and we reply with the rate per CFT.
- Delivery is quoted to your town separately. We supply across Tamil Nadu and into Kerala, Karnataka and Andhra Pradesh.
Common questions
Do I need an account to use it?
No - and you are not asked for anything at all. No sign-in, nothing to install, and the calculator does not save or send your list anywhere. It stays on your own phone.
How is the CFT worked out?
For sawn timber: CFT = width (in) x thickness (in) x length (ft) x pieces / 144. If you measure all three sides in inches instead, divide by 1728 - it is the same volume. Every line here is worked out that way and rounded down to four decimals.
Can I use it for a full lorry load?
Yes. Add as many sizes and lengths as you are loading, up to 200 lines, and the running total shows the pieces and the CFT for the whole load.
Can I use centimetres or metres?
The sheet works in inches and feet, as the trade does here. Convert before you enter them: 1 inch is 2.54 cm, 1 foot is 30.48 cm, and 1 CFT is 0.0283 CBM (1 CBM is 35.315 CFT). Ask us if you would rather we did it.
What about round logs instead of sawn sizes?
Logs are measured by girth and length, not width and thickness. Use our wood CFT calculator guide for those, or send us the girths on WhatsApp.
Is the CFT here what I will be billed?
The volume is worked out exactly the way we work it out, so the figures should match. The final bill depends on the sizes actually cut and the rate for the wood and grade you choose.
How do I get a price for these sizes?
Use the timber quotation page. It carries this same sheet with a Send button on it - add your sizes, sign in, and we reply with the rate per CFT; you can follow the quotation under your account. You also get a PDF of the list on our letterhead with a reference number.
For round logs, the wood CFT calculator guide has the girth formula and worked examples.
