How to Make a Wooden Phone Holder: DIY Plans and Step-by-Step Guide | Scrap-Wood Build

Three offcuts and one tube of construction adhesive are the whole bill of materials here. The published Bostik plan keeps the joint positions fixed, which matters more than it sounds — move the front ledge up half an inch and your cable stops fitting. The measurements below come straight from that plan, with the fit notes it leaves out.

What Wood and Tools Do You Need?

You need three pieces of scrap wood, a saw capable of a 45-degree cut, and a tube of Bostik No More Nails. The plan names no wood species, thickness, or saw type, so pick a hardwood offcut around 3/4 inch thick if you have one — pine dents, and the ledge takes the phone’s weight every day.

• Base: 6 × 3.5 inches
• Back support: 2 × 3.5 inches, one edge cut at 45 degrees
• Front ledge: two small square blocks (the plan gives no exact size; 1-inch squares work well)
• Adhesive: Bostik No More Nails, as the plan specifies
• Optional: paint or stain, applied after the adhesive sets

How Do You Cut and Assemble the Holder?

Cut all three parts first, dry-fit them, then bond — the plan’s joint positions are what make the stand work. Measure and mark the base at 6 × 3.5 inches and the support at 2 × 3.5 inches, then cut the 45-degree angle on one edge of the support.

2. Glue the two small blocks to the opposite face of the base, roughly 1.5 inches from the bottom. The gap between them and the base edge is the cable opening.
3. Let the adhesive cure per the tube’s label. The Bostik plan gives no specific cure time, so read your own tube.
4. Paint or stain once the joint is fully set.

That offset is deliberate — it tips the phone back against the support and holds the base of the device in the ledge.

Will Your Phone Actually Fit?

Measure your phone inside its case before you glue anything. The plan is not tied to any model or operating system — it is a passive wooden stand, so it fits whatever the ledge holds — but it also gives no maximum width, thickness, or weight.

For scale, an iPhone 15 is 2.82 inches wide and 0.31 inches deep at 6.02 ounces; the iPhone 11 runs 2.98 inches wide, 0.33 inches deep, and 6.84 ounces. Check the depth of your cased phone against the ledge height — the front blocks need to catch the bottom edge, not just touch it. The full plan is published by Bostik’s wooden phone holder guide.

If the fit is marginal and you would rather not sand and re-glue, a bought stand may suit better — this roundup of tested wooden phone holders covers stands built for cased phones.

What Goes Wrong Most Often?

The two failures that bite are a wrong angle and a blocked charging port. Skip the 45-degree cut, or guess at it, and the phone either slumps forward or sits too upright to watch comfortably.

• Front blocks too high. Keep them low.
• Ignoring the case. The most common miss. Bare-phone dimensions will tell you the ledge fits when it will not.
• Too much glue. Adhesive squeezes out along the joint and hardens into a visible ridge. A thin bead is plenty.
• Finishing too soon. Paint or stain over a still-curing joint locks in a weak bond. Wait out the label’s cure time.

Keep the holder away from heat and open flame, and treat it as a desk or shelf stand — the plan gives no vehicle-use approval, and a dropped phone in a moving car is not a risk worth taking. Eye protection and a stable, clamped workpiece matter when you cut the angle; the plan itself covers none of that.
