What is a split monogram SVG and how do you make one?

Spend any time on Etsy looking at laser engraving and you've seen them. A big decorative letter in the centre, two smaller letters on either side, the whole thing sitting inside a circle or a wreath or a pair of antlers. Sometimes the middle letter is literally split open and the frame tucks into the gap. That's a split monogram.

They sell constantly. People want them on cutting boards, tumblers, ornaments, tote bags. I started getting asked about them pretty early on and I'll be honest, when I first tried to make one from scratch I underestimated how fiddly it was.

Where the format comes from

Traditional monograms go back a long way. Three initials: first, last, first. The last name initial sits in the middle and is bigger than the two flanking letters. It's a Victorian convention that stuck around and got picked up again when personalised gifts became a serious market.

A split monogram takes that centre letter and slices it vertically so the frame or the side letters can sit in the gap. It looks more dimensional and it photographs well, which is probably why it took off on Pinterest the way it did.

Why building one from scratch takes so long

If you try to make a split monogram in Inkscape or Illustrator, here's what you're actually doing. Set the letter in a font. Convert it to outlines. Draw a vertical slice path down the middle. Use boolean operations to cut the letter into two halves. Size and position the flanking letters. Add a frame and position it so it sits correctly in the split. Then do it again for every letter in the alphabet, because your customers are going to ask for all of them.

It's doable. Plenty of people sell the results on Etsy. But it's a solid hour of work per letter done properly, and that's before you get into multiple fonts or frame styles. I did it the manual way for a while and it got old fast.

What makes a good one for cutting

Not every font splits cleanly. Thin script fonts fall apart when you slice them. The cut runs through thin strokes and the letter stops being readable. Bold serifs work well. Clean block letters work well. The centre letter needs enough weight that splitting it doesn't ruin it.

There's also a difference between engraving and cutting. An engraved monogram can have fine detail and that's fine. A cut monogram needs to stay in one piece, so the two halves of the split letter need to connect somewhere, usually through the frame. A properly built SVG handles that in the file so you don't have to think about it.

The builder I made because I got sick of doing it by hand

The monogram builder on this site generates the geometry for you. Pick your three initials, pick a font, pick a frame style and it builds the SVG live. You can see it before you download. The file has clean paths ready for Lightburn, Design Space, whatever you use.

DXF is available too if you're on a plasma table or a CAD workflow.

Getting narrow letters like I and J to split nicely is a different problem to wide ones like M and W. The builder handles that across the whole alphabet rather than treating every letter the same way. That was honestly the part that took me the longest to get right, and it's the part you never have to think about when you're using it.
