  • Accurate measurements are crucial: Always calculate total frame dimensions by considering photo size, mat borders, and frame thickness to ensure a perfect fit. 
  • Choose the right materials for the frame size: Thicker wood and acrylic sheets are recommended for larger frames, while thinner wood works for small and medium frames. 
  • Step-by-step assembly ensures quality: Cut corners precisely, glue and clamp pieces, and create a lip on the back to securely hold the acrylic, mat board, and photo. 
  • Mat boards enhance presentation: Carefully cut and position mat boards to prevent shifting and provide a polished, professional look for small, medium, and large frames. 
  • Secure hanging hardware appropriately: Small frames can use sawtooth hangers, medium frames may need D-rings with wire, and large frames require heavy-duty D-rings and possibly wall anchors. 
  • Finishing touches matter: Sanding, painting, staining, or varnishing ensures smooth edges and a professional appearance, making the frame both durable and visually appealing. 
  • DIY frames are versatile and customizable: You can repurpose materials, add decorative elements, or create themed designs, making handmade frames functional, creative, and personal.

Creating a picture frame may seem like a simple task, but designing one that fits perfectly, looks professional, and matches your space takes a bit of planning. Whether you want to frame a tiny snapshot, a standard photo, or a large piece of artwork, making your own picture frame can save money, give you creative control, and even become a fun DIY project. In this guide, we’ll cover everything you need to know about how to make a picture frame to fit small, medium, or large photos.

Why Make Your Own Picture Frame?

Why not just buy a frame? Making your own offers several advantages:

Before starting, it’s helpful to understand common photo sizes:

  • Small photos: 4×6 inches or 5×7 inches. Ideal for desk displays or small walls. 
  • Medium photos: 8×10 inches or 11×14 inches. Works well for galleries or living room walls. 
  • Large photos: 16×20 inches, 18×24 inches, or bigger. Perfect for statement pieces and art prints.

Knowing your photo size will determine the dimensions of your frame and the type of materials you need.

What Materials Will You Need?

Making a picture frame is easy if you have the right materials on hand. Here’s a basic list:

  • Wood strips or molding: Choose based on the size of your frame. Thicker wood works better for larger frames. 
  • Glass or acrylic sheet: Protects your photo. Acrylic is lighter and safer for larger frames. 
  • Backing board: Foam board or cardboard works well for supporting your photo. 
  • Wood glue or clamps: To secure corners. 
  • Nails or screws: Optional, for added stability. 
  • Measuring tape and ruler: Essential for accurate cuts. 
  • Saw (hand or miter saw): For precise corner cuts. 
  • Sandpaper: Smooth edges and surfaces. 
  • Paint or stain: Optional, for finishing. 
  • Hanging hardware: Hooks, wire, or sawtooth hangers depending on frame size.

How Do You Measure for a Custom Frame?

Accurate measurements are key to a well-fitting frame. Follow these steps:

  1. Measure the width and height of your photo. 
  2. Decide on the frame width (border thickness). Common widths: 1-2 inches for small frames, 2-4 inches for medium, 3-5 inches for large frames. 
  3. Add the frame width to the photo dimensions to calculate the outer frame size.

For example, a 5×7 photo with a 1-inch border on all sides will require a frame that is 7×9 inches externally.

What Tools Do You Need for Cutting and Assembling?

Precision makes a difference. These tools are recommended:

  • Miter saw: For clean 45-degree corner cuts. 
  • Hand saw: Suitable for smaller projects. 
  • Clamp set: Keeps corners in place while glue dries. 
  • Square ruler: Ensures corners are right-angled. 
  • Sandpaper or sanding block: Smooths edges and prevents splinters.

Step-by-Step Guide: How to Make a Picture Frame for Any Size

Below, we’ll break it down into small, medium, and large frames, so you can follow instructions specific to the photo size you’re working with.

How to Make a Small Picture Frame (4×6 or 5×7)

Materials Needed:

  • Wood strips (about 1 inch wide) 
  • Glass or acrylic sheet 
  • Foam board or cardboard for backing 
  • Wood glue and clamps 
  • Sandpaper 
  • Paint or stain (optional) 
  • Sawtooth hanger

Steps:

  1. Measure Your Photo: Measure width and height and add the frame border thickness (typically 1 inch). 
  2. Cut the Wood: Cut four pieces of wood at 45-degree angles using a hand saw or miter box. 
  3. Assemble the Frame: Apply wood glue to corners, join them, and clamp until dry. Optional: add small nails for stability. 
  4. Sand and Finish: Smooth edges with sandpaper. Paint or stain as desired. 
  5. Insert Glass or Acrylic: Cut to fit inside the frame. Clean before placing. 
  6. Add Photo and Backing: Center the photo on the backing board, insert behind the glass, and secure. 
  7. Attach Hanging Hardware: Use a sawtooth hanger on the back. Small frames are lightweight, so this is sufficient.

How to Make a Medium Picture Frame (8×10 or 11×14)

Materials Needed:

Materials Needed:

  • Wood strips (2-4 inches wide, thicker for support) 
  • Acrylic sheet (lighter than glass for safety) 
  • Foam board, mat board, and sturdy backing 
  • Wood glue, clamps, nails or screws 
  • Sandpaper 
  • Paint, stain, or varnish 
  • Heavy-duty D-rings and wire

Steps:

1. Determine Frame Dimensions

  • Calculate the total frame size by adding the photo size, mat board borders, and the width of the inner frame wood. For example, a 20″ x 30″ photo with 2.5″ mat borders and 1″ inner frame wood would require a frame roughly 27″ x 36″. 
  • Cut the inside frame slightly larger than the acrylic dimensions (about 1/8″ extra) to ensure everything fits comfortably, including the mat board and backing.

2. Build the Inside Frame

  • Cut the inner wood strips to size with 45-degree mitered corners. 
  • Apply wood glue to the corners and clamp the pieces securely until dry. 
  • Reinforce corners with nails or screws if needed for added stability.

3. Build the Outside Frame and Create a Lip

  • Cut additional wood strips to fit around the outer edge of the inside frame. 
  • Glue these outer pieces to the inner frame, using a small spacer to create a recessed lip on the back. 
  • This lip will hold the acrylic sheet, mat board, photo, and backing securely.

4. Cut the Acrylic Sheet

  • Cut the acrylic to the exact dimensions calculated for the frame. 
  • Keep protective film on during cutting to prevent scratches or chipping. 
  • Use a circular saw with a fine finish blade or a straight-edge utility knife for precision.

5. Cut the Mat Board

  • Carefully mark the overall mat size and the interior photo opening on the back side to avoid visible pencil marks. 
  • Use a sharp utility knife and a straight edge, cutting slowly to prevent chipping. 
  • The interior opening should be slightly smaller than the photo to hold it securely in place (for example, a 16″ x 20″ photo might require a 15.5″ x 19.5″ opening).

6. Assemble the Frame

  • Place the acrylic sheet into the lip of the frame. 
  • Position the mat board over the acrylic with the photo taped in place so it doesn’t shift. 
  • Add the backing board over the mat board. 
  • Secure all layers using frame tabs along the back edge; these tabs allow for easy photo swapping in the future.

7. Attach Hanging Hardware

  • Install heavy-duty D-rings and wire to support the weight of the large frame. 
  • Ensure proper placement and consider wall anchors for added security. 
  • For smaller hanging nails, use pliers to hold them steady when hammering.

8. Finish Touches

  • Sand edges and surfaces to remove rough spots. 
  • Apply paint, stain, or varnish evenly for a polished look. 
  • Check that all layers fit snugly and the frame sits flat against the wall.

Tips for Making All Sizes

  • Always double-check measurements before cutting wood or glass. 
  • Use clamps for precise corners. 
  • Keep sanding and finishing consistent for a professional look. 
  • Consider adding mats for small and medium frames to make the photo pop. 
  • Lightweight acrylic is preferable for medium and large frames to reduce risk of breaking.

Common Mistakes to Avoid

Even experienced DIYers can make errors. Avoid these pitfalls:

  • Incorrect measurements: Double-check dimensions before cutting. 
  • Poor corner alignment: Use clamps and a square for precise angles. 
  • Skipping sanding: Rough edges look unprofessional and can scratch the photo. 
  • Weak hanging hardware: Test weight limits, especially for large frames. 
  • Dust or fingerprints under the glass: Clean thoroughly before sealing.

Creative Variations

You can customize your frame to make it unique:

  • Paint techniques: Ombre, distressed, or patterned edges. 
  • Layered frames: Stack thinner strips for a shadowbox effect. 
  • Mixed materials: Combine wood and metal or incorporate fabric inserts. 
  • Themed frames: Add seasonal or decorative embellishments for holidays or gifts.

How Long Does It Take to Make a Frame?

Time depends on complexity and size:

  • Small frame: 1-2 hours. 
  • Medium frame: 2-4 hours including drying time. 
  • Large frame: 4-6 hours or more if finishing and reinforcement is required.

Can You Reuse Old Materials?

Absolutely! Repurposing old wood or frames is eco-friendly and cost-effective.

  • Sand and refinish old wood for a fresh look. 
  • Remove old hardware and replace with modern clips or hangers. 
  • Use leftover glass or acrylic sheets from previous projects.

Display Ideas for Your Handmade Frames

Once your frame is complete, consider creative ways to display it:

  • Gallery wall: Mix small, medium, and large frames for visual interest. 
  • Shelf grouping: Lean frames on shelves alongside books or plants. 
  • Rotating display: Swap photos seasonally to keep your decor fresh. 
  • Gift option: Handmade frames make thoughtful presents for friends or family.
