How to Make a Christmas Light Mockup From Your Own Photo
Shoot the house square-on in daylight, set the scale from a 16 ft garage door, draw the runs by type. Ten minutes, and the mockup carries footage and price.
A Christmas light mockup takes about 10 minutes from one photo you own: shoot the front square-on in daylight, set the scale from a 16 ft double garage door, draw each run by type, and the bulbs render along the runs. In GlowBid the same drawn runs carry the footage and the price, so the picture the homeowner approves is the quote they sign. Here is how we shoot, scale and draw it, with one two-storey worked to the total.
Strandr's mockup guide, published September 6, 2026, is a good 4,000 words on the picture. This page is shorter because it is about the picture that also measures and prices, and the photo rules for that are stricter.
What photo do you need for a mockup that also measures?#
A photo you own, taken square-on in daylight with the whole front and a garage door in frame. Every rule below exists because breaking it costs a second trip.
Rule
Why it matters
What goes wrong without it
Your own photo, or the homeowner's
You can keep it, draw on it, measure it and print it on the quote
Street View and satellite images belong to Google; their terms do not allow storing or tracing them, and the shot may be years old
Square-on from across the street
The eave runs parallel to the frame, so one 16 ft door scales the whole front
A diagonal shot shrinks the far side and every run over there reads short
Daylight, overcast if you can get it
The fascia is a crisp edge you can trace
Dusk hides the edge; bright sun blows out white siding and trim
Whole elevation with margin
Runs start and end where the roof does
Cropped corners mean guessed returns
A known length in the shot
The garage door sets the scale
No reference, no footage, only a picture
Phone level, no digital zoom
Straight verticals, sharp edges
Zoom smears the fascia line you need
Three shots, pick one at the truck
One of them will be level
The only shot is the crooked one
How to shoot it: stand across the street, centred on the front door, phone at chest height in landscape. Tap the fascia so the camera focuses on the edge, not the sky. Step back until the roof, the ground and the garage door are all in frame with a bit of margin. Take three. In snow country, get the photo before snow sits on the roof edge, or ask the homeowner for one from the summer. A maple in full leaf will hide a gable in August; shoot from the side of the tree or wait for the homeowner's spring photo.
Strandr's guide recommends shooting at civil twilight, which the U.S. Naval Observatory defines as the sun 6 degrees below the horizon, for a deep blue sky and glowing windows. It does look better. Shoot in daylight anyway, because the crisp roof edge is what turns a picture into a measurement, and the bulbs render on the runs either way. If you want the dusk shot for the homeowner, take both.

Why not just use Street View or a satellite image?#
Because you cannot keep it, and you should not measure from it. GlowBid shows a live Street View preview when you type the address so you can recognise the house and see which side the garage is on. That preview is display only: it is never stored, never drawn on, never measured. The canvas takes only photos you or the homeowner own. We wrote the reasons out in the Street View and satellite measurement rules. The short version: Google's imagery is Google's, it is often out of date, and a measurement from it is not one you can defend on the driveway. Your own photo costs you two minutes across the street and you can keep it for as long as the customer is yours.
Mark both ends of something you know the length of. On most houses that is the garage door: Clopay lists 8 ft and 9 ft as the common single widths and 16 ft as the classic double, so look before you type, and tape it if you are standing there. Strandr's measuring guide uses the same two references, an 80-inch entry door or a 16-foot double garage door. The longer reference wins; a 16 ft door gives a better scale than a 36 in front door.
That scale is true only for surfaces in the same plane as the door, which is the front face of the house. A side eave or a return that angles away from the camera reads short, sometimes by a third. GlowBid tags every run with its source (reference-scaled, in this case) and a confidence level, and puts a foreshortening warning on runs angled away from the camera so you type the real length from a tape or laser. The method is the same one in our roofline measuring guide; the mockup is that measurement with bulbs on it.
Draw the runs in the order you will install them, one type at a time, because each type prices differently:
Roofline. The eaves, corner to corner, including the short returns around each corner. The longest lines and the biggest line on the quote.
Peaks. Both sloped edges of every gable the customer wants lit. Slower, steeper, priced higher per foot.
Ridge line. The top edge of a gable, only if they asked for it. On seasonal work it is an upsell, not a default.
Jumps. The unlit cord between runs: across a valley, over the door, from a peak down to the eave. Drawn so the cord gets ordered, priced low because there are no bulbs on it.
Ground and trees. Walkway strands, bed edging, a wrap on the front tree.
Two rules on what to leave off. Draw only what the crew will install: a lit line over a cathedral peak your crew will not climb is a mockup you will have to walk back. And draw what they asked for first; the upsell is a second drawing, not a surprise on the first one.
Spacing comes from the bulb you install. Strandr's guide plans 1 bulb per foot plus 10 percent slack; GlowBid's default card assumes C9 at 12 in and a 10 percent materials buffer, the installer's choice, which never touches the customer's price.
The bulbs render along each drawn run on your photo, so the homeowner sees their own house, their own gables, lit where the crew will put the lights. Because the runs are drawn to scale, the same image carries a footage table by run type and, with a rate card, the price. Change a run and the picture, the feet and the dollars all change together. That is the difference between a mockup and a render: a render is a picture of lights, a mockup that measures is a bill of materials with a picture on it.
Send the homeowner one lit image, the footage table and the total. Not three colour options and no number. The number is what they were waiting for.
Worked example: a two-storey mockup that is also the quote#
A two-storey with a single-storey garage bump-out, two front gables, a walkway. Photo taken from across the street, scale set from the 16 ft double garage door. Every rate is GlowBid's default seasonal C9 card; installers set their own. You can price this house in the free tool with your own numbers.
Lit footage is 174 ft. With the 10 percent buffer the order is 192 ft of cord and, at 12 in spacing, 174 bulbs on the house and 192 ordered: 8 packs of 25 at Certified Lights' $19.95, $159.60 of bulbs. The quote PDF shows the drawing, that table and a line saying the footage is photo-based and confirmed on site. The homeowner approves the picture and signs the number on the same screen. How each rate was set is in our per-foot pricing guide.
Shooting from the driveway. Too close and too low; the eave converges and the upper runs read short. Cross the street.
Using a window as the reference. Windows vary by a foot house to house. Garage doors come in 8, 9 and 16 ft, and you can tape them.
Only taking the dusk shot. It looks great and the fascia is gone, so it cannot be scaled. That is a second trip for a daylight photo.
Digital zoom. It smears the roof edge into the sky. Walk closer or crop later.
Drawing the whole house when they asked for the front. The picture impresses and the number scares. Draw the ask, then offer the rest as a second drawing.
Snow on the fascia. A December photo of a bungalow with a snow lip reads 6 in high all the way along. Use a summer photo or draw to the gutter line and note it.
Forgetting the returns. The 3 ft pieces around each corner add 10 to 20 ft on a two-storey, and they are not on the mockup unless you draw them.
Sending a picture with no number on it. The next message is "so how much," and the answer comes from a spreadsheet. Send the total with the picture.
The free tool at glowbid.io/tools/roofline-measure is this whole method with no login until you export: drop a photo, set the reference, draw the runs, see the footage and the lights. The full product, open November 1, 2026, adds the rate card so the same drawing carries the price, the quote PDF with the drawing and footage by run, e-signature on the homeowner's phone, the Stripe deposit and the invoice. Core is $299 a year at the founding price, regular $499, with a 7-day trial and no card. If you compare mockup tools first, our roundup of drawn, AI and photo tools applies one test to each: can the render tell you how many feet to order.
FAQ
Questions installers ask
Can I make a Christmas light mockup from a Google Street View image?
No, and we built GlowBid so you never need to. Google's imagery is Google's: its terms do not allow storing, tracing or measuring it, and the shot is often years old with a car in the driveway. Use Street View to recognise the house, then take your own photo or ask the homeowner for one. That photo you can keep, draw on, measure and put on a quote.
What photo works best for a Christmas light mockup?
Your own photo of the front elevation, taken square-on from across the street in daylight, with the whole roofline in frame and a garage door visible. Overcast light is better than bright sun because the fascia stays a crisp edge. Keep the phone level and do not use digital zoom. Take three and pick the straightest one at the truck.
Do I need a dusk photo to show the lights at night?
No. A daylight photo gives you the crisp roof edge you need to trace and measure, and the bulbs render along the drawn runs on top of it. If you want a true dusk shot for the homeowner, take it at civil twilight, when the sun is 6 degrees below the horizon, but take the daylight one too. Measure from the daylight photo, never from the dark one.
How long does a mockup take?
About 10 minutes for a two-storey front once the photo is on the screen: two minutes to set the scale from the garage door, five to draw roofline, peaks, jumps and ground, and the rest checking the footage against what you can see. Strandr says its mockups average 2 minutes, and a picture alone can be that fast. Ours takes longer because it comes out with feet and dollars on it.
Can the homeowner take the photo themselves?
Yes, and for a phone quote it is the fastest way. Text them three rules: stand across the street in the middle of the house, hold the phone level and sideways, get the whole roof and the garage door in the shot. A photo they took is theirs to send you, and once you have it you can draw and measure on it. Confirm the footage on site the day you install.
Is the footage from the mockup accurate enough to order materials?
Close enough to quote and to order with a buffer, not close enough to skip checking on site. Runs in the same plane as the garage door come out within a few percent. Runs that angle away from the camera read short, and GlowBid flags those so you type the tape length. The default materials buffer is 10 percent, the installer's choice on the rate card, and the quote says the measurement is photo-based and confirmed on site.
