Practical wood tools, built by someone who worked in the timber trade.
Vriksai is an India-based startup — a set of 62 precise calculators for everyone who works with wood: woodworkers, carpenters, architects, timber traders and furniture makers. We are a small independent team, building tools that make everyday wood work faster, easier and more reliable.
The reason we made it is simple. People who work with wood keep doing the same maths again and again — board feet, volume, moisture, span, weight and cost. Most do it by hand, or use small online tools that are slow or give wrong answers. We thought, why not put all of these tools in one place, make them easy to use, and make them accessible to everyone. That is exactly what we are doing here.
What we believe
Accuracy over flash
Our calculations use formulas from documented technical sources and are checked against independently computed test values, with formulas and limitations explained on each tool page. We show the formula and the working so you can trust and audit the result.
Open access, no barriers
Every tool on the platform works without sign-up or login. Vriksai has applied to Google AdSense to help cover running costs; if ads go live in future, they will sit outside the tool result area and will never influence which species or tool is recommended.
Rooted in real wood
This is not a generic calculator site. Every tool lives inside the wood lifecycle, connected to the species, products and standards that surround it.
By the numbers
About the founder
My name is Deepak Kumar, and I started Vriksai. I have done my B.Tech in Computer Science Engineering, and I have spent more than 10 years working in digital marketing, website development, custom tools building and graphic design. So building websites and tools is something I know well.
The wood side is close to me too. I work in the wood industry in India, where I have gained hands-on exposure to timber imports, raw-wood processing and wood products, and that is where I really learned about timber. The company brings in wood from many international sellers, processes raw timber, and supplies it to customers who need raw wood. It also runs another brand that takes this raw wood and turns it into finished things like wooden panels, ceilings and decking, along with good quality wooden furniture. Being around all of this every day, I slowly understood how wood behaves, what people in this field actually need, and where they lose time.
That is what gave me the idea. I know wood from the inside, and I also know how to build digital tools. So I decided to bring both sides together and make something genuinely useful for the people who work with wood.
Our aim
Our aim is bigger than just a few calculators. We want to build a company that gives woodworkers, architects and traders every tool they need for their daily work, all in one place. We are only at the start right now, and we are a young startup, but we truly believe this can grow into something big and helpful for people all around the world.
If these tools save you time and make your work easier, then we have done what we set out to do. We are building this for the people in the wood trade, and we would be glad to have your support as we grow. If you spot a number that looks off, or you want a tool that does not exist yet, get in touch through the contact page.
How we build a tool
Every calculator on Vriksai starts with a real problem someone in the wood trade actually has. Nothing is built on speculation. Either a customer or supplier in the timber business has asked for it, or we have watched people lose time doing the same calculation by hand week after week. The problem comes first; the tool is the answer to it.
Once the problem is clear, we do the engineering work. That means finding the correct formula in a published source — the USDA Wood Handbook, the CIRAD tropical timber database, EN and IS standards, or peer-reviewed research — and understanding why the formula is what it is, not just copying numbers. A calculator whose author does not understand the equation cannot spot when the equation should not be used. This is why every tool page has a "Formulas" section, a "How the calculation works" explanation, and a Limitations block that tells you what the tool does not do. A hidden formula is a formula we do not trust either.
Then we build it. The interface is deliberately dense with inputs and light on decoration, because the people who use these tools are working — they want the answer, they want to see the working, and they want to move on. Every tool ships with a downloadable engineering report because a calculator that lives only on screen is useless when the site foreman asks for it in writing.
Finally, every published tool is regression-tested. Independent test values are computed from the formulas by hand, then compared against what the calculator returns. If the two do not match to the expected precision, the tool does not ship. The verification note on each tool page names the file that does this check.
How we source and verify data
Wood is a natural material, so every species figure has a range, not a single value. We are honest about that. Where the Wood Handbook says Scots Pine has a Janka hardness of 540 lbf and CIRAD says 550 lbf, we do not average them into a made-up number; we cite the source we are using and note that other authorities differ. The species pages list every source, and the reference library explains what each source is authoritative for and what it isn't.
Our primary sources, in order of weight:
- USDA Forest Products Laboratory Wood Handbook — the standard reference for North American and many European species. Density, strength, shrinkage figures.
- CIRAD Tropix database (French Agricultural Research Centre for International Development) — the equivalent for tropical species where the USDA data is thin or absent.
- International ThermoWood Association — for all ThermoWood-classified species; the ThermoD and ThermoS process results are theirs.
- Indian Standards (IS 883, IS 1708) and Institute of Wood Science and Technology (IWST) publications — the correct reference for Indian species and for design in the Indian regulatory context.
- Peer-reviewed journals (Wood Science and Technology, Journal of Wood Science, Forest Products Journal, Holzforschung) — for species or properties the handbooks do not cover.
Where a figure could not be verified against at least one of these, the page says so and shows the calculation without pretending to a certainty we do not have. Publishing a number we cannot back is worse than saying we do not know.
Editorial and accuracy standards
We have written down how the site is run. The editorial policy covers how content is written, reviewed and dated. The accuracy policy explains how figures are checked and how we handle corrections. The source methodology lists every source we cite and why we cite it. None of this is decoration — if you find an error, those policies commit us to fixing it and dating the fix in public. Report it through the contact form or the Report a Bug link in the footer of every page and it is acknowledged within one working day.
Every published page carries the author byline — not to inflate credibility, but so a reader can see who is responsible for the number they are about to base a decision on. Anonymous technical content is a warning sign; we do not want to be a warning sign.
Who we build for
Five kinds of user shape everything on this site:
- Carpenters and cabinetmakers — joinery layout, board feet, shrinkage, screw and dowel capacity, drawer geometry. The tools that answer the questions that come up on the bench and at the saw.
- Architects and interior designers — sag under load, expansion gaps, species suitability for a use, cost per cubic foot. The tools that answer questions before drawings are issued for construction.
- Timber traders and importers — volume conversions between Hoppus, board foot and cubic metre, log scaling rules, green-to-dry weight conversions, kiln schedules. The tools that answer questions on the yard, at the docks and in the LC negotiation.
- Furniture manufacturers — batch drying, moisture tracking, panel expansion, adhesive coverage, hardware positioning. The tools that answer questions on the shop floor.
- Wood-industry students and researchers — the species database, formulas library and reference articles are there to be studied, not just used. Our formulas are documented and cited where a source is available, and derived methods are identified, so they are teachable.
If you fit one of these descriptions and something you need is not on the site yet, that is exactly the information we want. Every gap someone tells us about becomes a candidate for the next release.
How we are funded
The core tools are accessible today without sign-up. As the platform grows, some advanced features may move to a paid tier, but the goal is to keep everyday calculators available to everyone who needs them. Running a site like this — the servers, the domain, the tools that host the code, the time spent researching and writing — costs money. Vriksai has applied to Google AdSense to help cover those running costs. Ads are not currently served on this site. If and when they go live, any ad will be clearly marked as advertising and will sit outside the tool result area — never inside a result panel, never influencing which species or which tool is recommended, and never dressed up as content. If a species is ranked first, it is because the engine ranked it first for the criteria you entered — nothing else changes that.
We do not sell email lists, we do not sell user data, we do not run affiliate schemes on the tool pages, and we do not accept payment to feature a supplier or a species. If that ever changes, the change will be published on this page and dated. The full data-handling detail is on the privacy policy and the cookie policy.
