Lumber Futures Contract Specifications (LBS)
Soft commodity futures cover food and fibre crops grown in specific origins. Contract size, tick size and delivery terms are all set by the exchange and vary considerably between contracts.

Margin is not listed here on purpose — the exchange revises it and every broker adds its own buffer. Check your broker's platform for the live figure. Use the margin calculator to estimate what a position will tie up.
Doing the tick math
One tick is 0.50 in the quoted price, which is $13.75 per contract. A move of one full point (1.00 in the quoted price) is worth $27.50, so there are 2 ticks in a point. Get those two numbers wrong and every risk calculation downstream is wrong, which is the point of the tick value guide.
Enter your own prices in the tick value and P/L calculator to see the dollar result for this contract without doing the arithmetic by hand.
Delivery months
F,H,K,N,U,X — January, March, May, July, September, November. Liquidity concentrates in the nearest active month; open interest migrates over a few weeks before expiry, which is what the roll mechanics guide walks through.
What one tick is worth at different position sizes
The per-tick figure scales linearly, which is the part most traders get wrong when they add contracts without re-checking risk.
| Position | Value of 1 tick | Value of 10 ticks |
|---|---|---|
| 1 contract | $13.75 | $137.50 |
| 2 contracts | $27.50 | $275 |
| 5 contracts | $68.75 | $687.50 |
| 10 contracts | $137.50 | $1,375 |
Ten ticks on a LBS contract is a move of 0.50 × 10 in the quoted price. If you want the P/L for a specific entry and exit rather than a tick multiple, put the prices into the tick value calculator.
Converting your stop into a dollar risk
Stops are set in price terms but risk is booked in dollars. Multiply the stop distance in ticks by the tick value — and then add commission, which is charged per contract per side and is not in the numbers below.
| Stop distance | 1 contract | 5 contracts |
|---|---|---|
| 5 ticks | $68.75 | $343.75 |
| 10 ticks | $137.50 | $687.50 |
| 20 ticks | $275 | $1,375 |
| 40 ticks | $550 | $2,750 |
On a 27,500 board feet contract, a 20-tick stop at one contract ties up $275 of risk before costs. At five contracts it is $1,375. This is why position size should follow the stop, not the other way round — the arithmetic is laid out in choosing a futures contract.
How margin is set on Lumber futures
Margin is not a property of the contract spec — it is a risk parameter the exchange recalculates periodically and that your broker then marks up. Two consequences follow:
- The figure moves when volatility moves, so a margin number copied from a blog post is usually stale.
- Two brokers can require different amounts for the same LBS contract.
What is fixed by the spec is the notional exposure: 27,500 board feet multiplied by the price. Margin is a percentage of that notional, which is why a higher price or a wider exchange buffer raises the cash requirement without the contract itself changing. The margin calculator takes your broker's number and converts it into "how many contracts can I hold"; the mechanics are in how futures margin works.
Where these numbers come from
Contract unit, tick size and delivery months are taken from the contract specifications published by CME. Exchanges occasionally change tick sizes and listing months, so before relying on this page for a live position, check the current spec sheet on the exchange's own product page or on your broker's platform. This page was last rebuilt on 15 November 2026.
