Print a Locket Size Photo
Printing a locket-size photo at home or through commercial print labs requires miniaturizing a standard high-resolution digital image down to a precise fraction of an inch—typically between 12mm and 20mm (0.5 to 0.75 inches). Because lockets feature tiny, non-standard shapes like ovals, hearts, and circles with recessed rims, mastering image scaling, millimeter sizing, and photo paper selection ensures your cherished keepsake fits with jeweler precision.
Locket Shapes, Millimeter Sizes, and Proportions
Lockets are deeply sentimental jewelry heirlooms designed to carry photographs of children, spouses, late parents, or beloved pets close to the heart. However, attempting to scale an 8x10 portrait down to fit a tiny vintage locket often results in frustration: heads get cropped off, resolution pixelates, or photos print far too large.
The secret to successfully printing a locket photo is creating a multi-scale digital contact sheet. By generating multiple copies of the image scaled incrementally by 5% increments on a single 4x6 photo sheet, you guarantee that at least two prints will match your locket bezel perfectly.
Examine standard jewelry locket dimensions and their millimeter conversions:
| Locket Silhouette Shape | Standard Millimeter Size (Inside Bezel) | Approximate Inch Dimension | Head-to-Chin Target Height | Cropping Best Practice |
|---|---|---|---|---|
| Small Heart Locket | 12mm wide x 12mm tall | Approx. 0.47" x 0.47" | 5mm to 6mm head height | Zoom out; keep subject centered away from top heart cleft |
| Medium Oval Locket (Classic) | 15mm wide x 20mm tall | Approx. 0.60" x 0.78" | 8mm to 10mm head height | Leave ample negative headroom above hair |
| Large Oval Locket | 20mm wide x 25mm tall | Approx. 0.78" x 0.98" | 12mm to 14mm head height | Can comfortably accommodate two close faces |
| Small Round / Circle Locket | 14mm Diameter | Approx. 0.55" Diameter | 6mm to 7mm head height | Keep face tightly centered within square crop |
| Rectangular / Book Locket | 14mm wide x 18mm tall | Approx. 0.55" x 0.70" | 8mm to 9mm head height | Vertical portrait orientation; leave edge margins |
Methods for Sizing and Printing Locket Photos
The most common pitfall when sizing a locket photo is choosing a portrait where the subject's face fills the entire camera frame. When an image is shrunk down to 15 millimeters, tight close-up portraits leave no border room for the locket's curved bezel rim or heart lobes. Always start with a photo taken from the chest up with generous background space surrounding the subject's hair and shoulders.
Paper selection makes a dramatic difference in both clarity and ease of insertion. Do not print on regular 20lb office copier paper; plain paper absorbs inkjet dyes, causing blurry, muddy facial features. Conversely, heavy cardstock or ultra-thick commercial photo paper is too rigid to slide under the microscopic lip of a locket bezel. The ideal medium is a medium-weight premium glossy or semi-gloss photo paper (approximately 180 to 200 GSM).

Strategic Guidance and Expert Recommendations
To make an exact physical template of your locket's interior, place a piece of thin tracing paper or parchment paper over the open locket well. Take a soft graphite pencil and gently shade over the opening. The raised metal lip will create an embossed pencil impression of the exact cavity contour. Cut out this paper rubbing with curved manicure scissors to serve as your physical cutting stencil.
To protect the delicate printed emulsion against body heat and humidity, apply a protective laminate layer. Cover the tiny cut photo with a small strip of clear glossy tape before trimming, or coat the surface with a microscopic dab of clear jewelry glaze or Mod Podge. This seals the ink, preventing it from sticking to the facing glass or fading over time.
How to Print and Insert a Locket Photo Step by Step
Follow this precision jeweler method to size, print, trim, and install a photo inside a locket.
Create a Paper Rubbing of the Locket Cavity
Lay thin tracing paper over the open locket well and rub gently with a soft pencil to capture the exact oval or heart rim contour.
Measure Cavity Width and Height in Millimeters
Use a clear plastic ruler to measure the exact millimeter width and height of the paper rubbing (e.g., 15mm x 20mm).
Scale Photo in Microsoft Word or LocketStudio
Insert your photo into Word, right-click, select Size, and set height to match your measurements; paste 6 copies at slight scaling increments.
Print on 4x6 Glossy Photo Paper
Print the multi-size contact sheet at maximum print resolution (600+ DPI) on glossy photo paper at home or a local print kiosk.
Trim with Curved Manicure Scissors and Seat Photo
Use the paper stencil to trace and trim the photo with precision manicure scissors, slipping the edges under the locket's bezel lip.
Frequently Asked Questions (7 Questions Answered)
Q1: What size photo fits in a standard locket?
Most standard medium lockets take photos measuring between 15mm x 20mm (roughly 0.6" x 0.8"), while small lockets require 12mm x 12mm.
Q2: What is the easiest way to size a photo for a locket?
Using free online locket-sizing tools like OddPrints or LocketStudio is the easiest method; they automatically scale your picture to standard millimeter sizes on a 4x6 print.
Q3: What paper should you print locket photos on?
Print on medium-weight glossy photo paper (180-200 GSM); it provides crisp photo resolution while remaining thin enough to flex into the bezel.
Q4: How do you cut a photo to fit an oval or heart locket?
Make a pencil rubbing of the locket opening on tracing paper, cut it out as a stencil, lay it over the photo, and trim using curved manicure scissors.
Q5: What holds the photo inside the locket?
Lockets feature a recessed channel lip (bezel rim) that holds the photo; some include a clear plastic protective lens that snaps over the image.
Q6: Can you use a phone app to size locket photos?
Yes, apps like Locket Studio allow you to select your locket shape, measure dimensions, and export a ready-to-print photo sheet to your camera roll.
Q7: Should I glue the photo into the locket?
Avoid liquid glue, which warps photos; if the photo is slightly loose, use a tiny speck of double-sided scrapbook tape or removable adhesive putty.
