LEGO Mosaic Answers

The BMBrick digital blueprint costs $9.90 as a one-time unlock. Physical bricks are purchased separately through your chosen sourcing channel. A 48×48 mosaic typically runs $35–55 via LEGO Pick a Brick at $0.06 per piece, a 64×64 costs $60–100, and a 96×96 ranges from $130–220. The actual total depends on the color mix, sourcing route, and whether you remove the background to reduce wasted bricks. BMBrick shows a cost estimate before you unlock so you can decide whether the project fits your budget. Read more in How Many Pieces?.

Start with a 48×48 size to keep the piece count at 2,304. Use LEGO Pick a Brick at $0.06 per 1×1 plate for the most predictable pricing. Before generating, remove the photo background with Magic Cut so the mosaic only uses bricks where the subject actually is. Fewer background bricks means fewer parts to buy. If you need even more colors at similar prices, Webrick offers about 60 colors with fixed pricing and direct shipping. Avoid BrickLink for budget builds unless you already know how to find bulk deals across multiple sellers. Read more in PAB vs BrickLink.

BMBrick charges a one-time $9.90 fee per blueprint unlock. There is no subscription, no recurring charge, and no per-month plan. You can upload photos, adjust crop and settings, preview the mosaic, and review the palette entirely for free. The fee only applies when you want to export the full package: PDF build instructions, BrickLink XML, PAB CSV, Webrick CSV, and the structure BOM. One unlock covers all export formats for that specific mosaic design. Read more in Why BMBrick.

At least 500×500 pixels, though higher is always welcome. The mosaic grid is only 48–96 studs wide, so extreme resolution does not add visible detail once the image is quantized down to brick colors. What matters far more than pixel count is subject clarity, lighting quality, and contrast between the subject and background. A well-lit smartphone photo with a clear face and simple background will almost always produce a better mosaic than a high-resolution image shot in dim light with a cluttered scene behind the subject.

Blurry photos lose facial features and edge definition when reduced to mosaic resolution. Low-light photos compress shadow detail into a narrow tonal range that the limited brick palette cannot distinguish, so dark areas tend to merge into a single flat color. If the photo is slightly soft, try increasing sharpness and contrast in any photo editor before uploading. If the lighting is poor, boost brightness and reduce shadows. Choosing a larger mosaic size like 64×64 also helps because more studs means more room to represent subtle tonal differences. Read more in Choose the Right Photo.

Yes, in most cases. Background removal reduces the total number of bricks needed, which directly lowers cost. It also makes the subject more recognizable at smaller mosaic sizes because the engine can dedicate all available colors and detail to the subject instead of wasting palette entries on background tones. BMBrick includes Magic Cut, a browser-based subject isolation tool that runs entirely on your device. No image data is uploaded. For portraits, pets, and product shots, background removal is almost always worth doing before generating the final mosaic. Read more in Pet Portrait Guide.

Exactly 2,304 pieces. Each stud position in a 48×48 grid holds one 1×1 tile or plate, so the total is 48 multiplied by 48. A 64×64 mosaic uses 4,096 pieces and a 96×96 uses 9,216. BMBrick calculates the exact count and full color breakdown after you generate the preview, so you know precisely how many of each color you need before ordering. The parts list export files include per-color quantities formatted for your chosen sourcing platform. Read more in How Many Pieces?.

Part 3024 is a square 1×1 plate that sits flush against its neighbors, creating a smooth and continuous surface. Part 98138 is a round 1×1 tile with a raised circular dot on top, giving the mosaic a more textured, pixelated appearance reminiscent of classic pixel art or LED displays. Square plates generally work better for portraits and images with smooth gradients because the flat surface preserves tonal transitions. Round tiles suit retro-style designs, logos, and images where a deliberate dot-matrix look is part of the aesthetic. Read more in Square vs Round.

It depends on the sourcing route. LEGO Pick a Brick currently offers 42 colors for 3024 square plates, all at a fixed $0.06 per piece. Webrick extends the palette to about 60 colors including some specialty finishes, also at fixed pricing. BrickLink has the widest selection because it aggregates thousands of individual sellers worldwide, but prices and stock levels vary by color and seller. BMBrick shows which colors are available on each route so you can see exactly what palette you are working with before committing. Read more in LEGO Colors Guide.

After unlocking your blueprint, open the export panel and click the BrickLink XML button. BMBrick generates an .xml file containing every color and quantity your mosaic needs, formatted for BrickLink’s Wanted List import. Download the file, go to BrickLink, navigate to your Wanted List, choose Upload, and select the XML. BrickLink will parse the file and let you add all items to a list so you can find sellers who stock the parts. You can then use Easy Buy or manual cart-building to place your order.

Pick a Brick is best for standard builds: fixed $0.06 per piece, official LEGO quality, and direct shipping. BrickLink is best when you need rare or discontinued colors, want to compare prices across sellers, or are buying in very large quantities where per-piece savings add up. Webrick offers the widest standard color palette at fixed pricing with direct shipping, making it a good middle ground. BMBrick generates the correct export file format for each platform so you do not need to manually convert anything. Read more in PAB vs BrickLink.

Yes. The mosaic design is based on a standard 1×1 stud grid, so any brand that produces compatible 1×1 plates or tiles will work. Webrick and other third-party manufacturers offer parts that match LEGO dimensions at competitive prices, often with a wider color selection. BMBrick’s export files specify colors by standard color codes, and the PDF instructions use symbol-based legends that work regardless of which brand you build with. The physical result will look the same as long as the parts match the 1×1 footprint. Read more in Baseplate Guide.

No. All image processing happens locally in your browser using client-side JavaScript and Web Workers. Your photo is loaded into browser memory, processed there, and never transmitted to any external server. BMBrick does not have a backend image pipeline, does not store uploads, and does not use cloud-based image processing. The only network requests the app makes are for loading the page assets themselves. This local-first architecture means your personal photos stay on your device throughout the entire workflow. Read more in Why BMBrick.

No. BMBrick does not persist your mosaic design on any server or in any database. The design exists only in your active browser session. If you close the tab or navigate away, the session data is gone. This is by design: it ensures your creative work and personal images are never retained without your knowledge. Always export your PDF instructions, parts list files, and any other outputs you need before closing the page. Once exported, those files live on your device under your control. Read more in Why BMBrick.

No. Since all processing runs entirely in your local browser, there is no server-side copy of your image that anyone else could access. BMBrick has no gallery feature, no sharing mechanism, and no user accounts that could expose your uploads. Your photo stays on your device from the moment you select it to the moment you close the tab. The only way someone else could see your mosaic is if you choose to share the exported files yourself.

48×48 works well for a single person or pet portrait where the face fills most of the square crop. It keeps cost under $55 and build time under five hours, which is manageable for a first-time builder on a deadline. 64×64 is better for couples, detailed portraits, or when you want the recipient to see finer features like eye highlights or hair texture. Budget and available wall space are the main constraints. For most gift scenarios, 48×48 or 64×64 hits the right balance of cost, build time, and visual impact. Read more in Wedding Gifts.

Yes, and wedding photos often work especially well because formal attire creates strong contrast against most backgrounds. Recommend 64×64 or larger for couple shots so both faces retain enough detail to be recognizable. Crop tightly around the couple rather than including the full venue scene. Consider removing the background to focus all available colors on the subjects. If the photo includes a veil or other fine detail, a larger size preserves those elements better. Wedding mosaics make popular anniversary and housewarming gifts. Read more in Wedding Gifts.

Roughly 3–5 hours for a 48×48, 5–8 hours for a 64×64, and 10–16 hours for a 96×96. These estimates assume pre-sorted parts and printed PDF instructions. The biggest variable is color complexity: a mosaic with many similar neutral tones takes longer per module than one with bold, distinct colors. Plan an additional 1–2 weeks for parts shipping from your chosen supplier. For gift deadlines, order parts early and build in short verified sessions rather than attempting one long marathon.

If you can follow a numbered grid, you can build a mosaic. BMBrick’s PDF instructions use symbol legends and 16×16 module pages so you only need to focus on a small section at a time. No special artistic skill, engineering knowledge, or prior LEGO experience is required. The main challenge on larger builds is maintaining patience and accurate color sorting over multiple sessions, not the complexity of the assembly itself. Starting with a 48×48 single-subject mosaic is the most forgiving entry point for beginners. Read more in First LEGO Portrait.

A flat, well-lit work surface is essential. You will also need small containers or trays for sorting bricks by color so you can grab the right piece without searching. The printed or on-screen PDF instructions serve as your build guide. No glue, no cutting tools, and no special equipment are required. A standard LEGO brick separator is helpful for correcting misplaced pieces without damaging them. Good overhead lighting matters more than most builders expect, especially for mosaics with many similar neutral tones. Read more in Anti-Fatigue Builds.

Work in 16×16 modules and verify each module against the instruction page before moving to the next one. Sort all colors into separate labeled containers at the start of each session so you never rely on memory to distinguish similar shades. Take breaks every 45–90 minutes to keep your eyes fresh. End each session at a clean module boundary rather than stopping in the middle of a face or transition zone. If a module looks wrong, fix it immediately rather than hoping the error will blend in later. Read more in Anti-Fatigue Builds.
