Frequently asked questions
Is the configurator free to use
Yes, the configurator on the homepage is free with no account or email required. Enter a length, width, and height, pick a wood species, and get a cut list, boards to buy, hardware, and soil volume.
Why is the end board shorter than the width I entered
The long boards run the full outside length, while the end boards sit between them at a butt joint, so each end board is the width minus twice the board thickness, about 3 inches total for a standard 2x6. The configurator calculates this automatically from the actual milled board thickness.
Do I need a center brace
The configurator adds a center brace once the length or width reaches 84 inches, since a long unsupported wall can bow outward once the bed is filled with wet soil. Shorter beds do not need one.
What is the difference between the free plan and the paid Build Pack
The 4x2 Starter Plan is a one page printable plan for the most common first bed size, free after providing an email address. The Raised Bed Build Pack is a paid, more complete document with six full plans, exploded views, hardware guides, build variants, and a wood chapter.
Does the soil calculation include the corner posts
No, the soil volume is based on the interior floor area and the wall height, which is the space the posts and boards actually enclose, not the outside footprint.
Where do I download the Raised Bed Build Pack after purchase
The download link is provided immediately after a successful payment and also sent by email. See the files page and the order page for details.
Build procedure and order of work
Work on a flat surface large enough for the longest side of the bed, with at least 24 inches of clear space on all sides. Sort the boards first. Put the straightest boards on the top course, where a bowed edge is easiest to see and hardest to correct later.
Mark all cuts before using the saw. Measure from one reference end only, not from both ends, because small pencil and saw errors can add up to 1/8 inch or more across several pieces. After cutting, stack matching boards together and label them with pencil as long side, short side, post, or brace.
Assemble one long wall first. Clamp the board to the posts, check that the post is flush with the board end, then drill pilot holes before driving screws. A useful pilot hole for a common exterior screw is about 1/8 inch, but match the drill bit to the screw shank, not to the screw threads. Keep screws at least 3/4 inch from the board edge to reduce splitting.
Build the second long wall the same way, then connect the two walls with the end boards. Check both diagonals before the final screws are tightened. If the two diagonal measurements differ by more than 1/4 inch on a bed up to 8 feet long, push the longer diagonal inward until the frame is square.
Tools, hardware checks, and working dimensions
The work is easier if the bed is built with ordinary carpentry tools, but accuracy matters more than tool cost. A circular saw can cut the parts, a miter saw only makes repeat cuts faster. A drill and a driver are useful as separate tools, because one can hold the pilot bit and the other can hold the screw bit.
- Use a tape measure that locks firmly and read every mark from the same side of the blade.
- Use a speed square or framing square to mark 90 degree cuts on posts and boards.
- Use two clamps at least 6 inches long to hold boards while fastening.
- Use corrosion resistant exterior screws, and choose a length that gives strong bite into the post without exiting the opposite face.
- Use gloves when handling rough lumber, and use eye protection when cutting or drilling.
Common lumber sizes have actual dimensions smaller than their name. A 2x6 is usually about 1.5 inches thick and 5.5 inches tall. A 2x8 is usually about 1.5 inches thick and 7.25 inches tall. If a plan uses two stacked 2x6 courses, the wall height is about 11 inches before any cap or ground contact is considered.
| Item to check | Useful figure | Why it matters |
|---|---|---|
| Diagonal difference before final fastening | Less than 1/4 inch for a typical 4 by 8 foot bed | Keeps corners square and boards seated correctly |
| Minimum screw distance from board end | About 1 inch | Reduces end splitting during assembly |
| Minimum screw distance from board edge | About 3/4 inch | Prevents the fastener from tearing out the edge grain |
| Clear working space around frame | About 24 inches | Allows clamping, drilling, and squaring without moving the frame repeatedly |
| Expected build time for one simple bed | 2 to 4 hours after lumber is on site | Allows time for sorting, cutting, drilling, and squaring |
Frequent mistakes and how to recover
If a board was cut short by less than 1/4 inch, do not stretch the frame to hide the gap. Keep the frame square and place the small gap at a low stress joint. If the cut is short by more than 1/2 inch, recut the part if spare material is available, or shorten the matching part on the opposite side only if the final outside size can change.
If a screw splits the end of a board, remove the screw and clamp the split closed. Drill a larger pilot hole, then drive a new screw at least 1 inch away from the split line. If the split remains open after clamping, replace that board or move it to a lower course where it is not carrying the clean top edge.
If the frame rocks on the ground, do not force the corners down with screws. The frame is probably flat and the site is uneven. Remove high spots in the soil first. A difference of 1/2 inch across the bed can usually be corrected with a shovel and rake in a few minutes. Larger differences should be stepped, terraced, or leveled before filling.
If the bed bows after filling, remove soil down to half height before adding reinforcement. Fastening a brace against full wet soil load can strip screws or pull boards out of line. Once the pressure is reduced, pull the sides straight with a clamp or temporary strap, then install the brace and refill in layers.
Special cases to plan before cutting
For a bed placed against a fence or wall, leave at least 18 inches of access on the hidden side if that side needs screws, stain, or later repair. If there is no access, assemble that wall completely before moving the bed into place.
For a sloped site, decide whether the top of the bed or the bottom of the bed must be level. A level top looks cleaner and makes watering more even, but it may require one side to sit deeper in the soil. On a slope greater than about 1 inch per foot, a stepped layout is usually easier to build than one tall frame set into the hill.
For very soft soil, set the bed on compacted ground before filling. Loose soil under one corner can settle after rain and twist the frame. Tamp the corners and the middle of each long side, then check level again before adding soil.
For beds near irrigation lines, mark the pipe path before driving stakes, posts, or anchors. Keep fasteners and stakes several inches away from the line, and take a photo of the empty bed location before filling so the pipe route is still known later.
